OBD-II Code Declined engine performance is a means of a Cylinder 1 Exhaust Valve Control Circuit Low.

The extremity of this code can differ immensely from relative to extreme that relies on the particular symptoms of the function break. A misfire needs instant attention as it can lead to perpetual damage to interior engine parts.

In the attempt to encounter fuel and emissions values, numerous manufacturers are using cylinder deactivation procedures. These methods allow the engine's control module (PCM) to deactivate chosen cylinders when power that is not needed is added by the engine, such as at idle or when riding down the highway. If the engine's control module (PCM) finds out the Exhaust Valve for cylinder number 1 is not turning ON or OFF in the manner it is ordering, the PCM will place code P3407.

What causes this problem with the Cylinder 1 Exhaust Valve Control Circuit Low?

• Defective variable valve timing solenoid
• Dropped engine oil level or pressure
• Limited oil passage
• Defective or damaged wiring
• Loose, corroded or damaged connector
• Faulty ECM

1. ECM - An illuminated Check Engine Light is a major sign of an error related to the Engine Control Module. The Check Engine Light normally starts to illuminate when the computer detects an error that is related to all the sensors or circuits. In some circumstances, the ECM triggers a Check Engine Light by mistake, or if there is no present issue. Doing a scan on the computer for error codes can assist with detecting whether or not there is a problem with the ECM, or the finding out where the problem is located on the vehicle. Irregular engine behaviour is another major sign of a faulty or failing ECM. A failed computer could lead to a vehicle that encounters irregular issues such as stalling or misfiring. These symptoms might come and go, and might not show any kind of sequence to their persistence or extremity. Engine operation problems are another major sign of a critical error related to the ECM. If the ECM encounters any problems, it might lead to timing and fuel settings to negatively affect the operation of the vehicle. A defective ECM might lead to the vehicle dealing with a decrease in fuel efficiency, power, and acceleration. A vehicle that fails to start or prevents restarting is another major sign of a faulty or failed ECM. If the ECM fails entirely, the vehicle will stay dealing with a loss of engine power control, and will fail to start or perform as an outcome. The engine might still be cranking, but will fail to start if being faced with the missing vital inputs from the computer. A vast range of other problems can also prompt this symptom, so it’s a good idea to do a rigorous diagnosis that is accomplished by a professional mechanic that will continue at detecting the result.
2. PCM - An illuminated Check Engine Light is a major sign of a problem that is related to the Engine Control Module. The Check Engine Light regularly comes on as the computer checks a problem related to all of the sensors or circuits. These are cases when the ECM activates a Check Engine Light to illuminate by mistake, or when no present issue is evident. Ensure a mechanic scans the computer for trouble codes to diagnose whether the issue is associated with the ECM, or another area inside the vehicle. Abnormal engine operate could also identify a defective or failing ECM. A faulty computer could result in the vehicle to stall or misfire irregularly. The symptoms might come and go, but not display a specific behaviour under any type of pattern of their consistency or extremity. Engine operation problems are another symptom of a crucial problem related to the ECM. If the ECM is facing any issues, it leads to timing and fuel settings within the engine to negatively affect the operation system. A faulty ECM might result in the vehicle to experience a reduction in fuel efficiency, power, and acceleration. A bad ECM could result in a vehicle that fails or prevents starting. If the ECM fails completely, the vehicle will remain without any engine management control, and will start or perform as a result. The engine could still be cranking, but it will restart, and not sustain any crucial inputs from the computer. The ECM will not completely lead to any problems in starting the vehicle, so it is best to conduct a diagnosis by consulting with a professional mechanic to persist in checking the final outcome. A bad fuel economy could transpire when the ECM fails. A faulty ECM refuses the engine from being familiar with the quantity of fuel burning inside the combustion system. Regularly, the vehicle consumes more fuel than it demands in this scenario. As an outcome, you will be paying more money on fuel than you need to with a running ECM.
3. Exhaust Valve - A major indicator of an error with the exhaust pressure valve is an engine operation problem. If the valve gets plugged or obstructed it can affect the engine operation. A defective exhaust pressure valve might result in the vehicle to experience a decrease in power; possible issue with the exhaust pressure valve is too much smoke or soot released from the exhaust. Concerning diesel engines building up with these parts, the exhaust pressure valve has a crucial job for the inside of the correct engine combustion. These types of problems can disrupt the readily fragile combustion system of diesel engines, which might result in black smoke and soot getting released from the exhaust pipe. A Check Engine Light that illuminates is another symptom of a viable problem related to the exhaust pressure valve. If the computer identifies a problem with the exhaust pressure valve’s circuit, signal, or position, then it will activate a Check Engine Light in a way to warn the driver of a possible error. A Check Engine Light that illuminates will also place a vast extension of other problems, doing a scan on the computer for error codes is highly advised.
4. Engine Oil - If the cold thickness of your oil is too much, and so very thick, then you could fail to start your vehicle under any cold climate. When this often happens, it causes the oil to get much thicker to an extent it fails to properly lubricate all moving parts and thus results in excessive resistance as the vehicle is starting. If you expend synthetic oil inside a vehicle with older or higher mileage, you might start to accumulate small oil leaks that you wouldn’t have received if you had been using conventional motor oil. This is all due to of a range of flow attributes that synthetic oils obtain, which conventional oils don’t obtain. It allows the oil to push its way into tighter gaps than normal oil. Consuming synthetic oil in these cases will not ultimately result in any kind of damage, so you could be seeing drops of oil spewed on your garage floor or a burning smell when you are driving. As this oil slowly leaking, you might want to pay more attention to your oil level and make sure it’s topped off when needed. Switching back to conventional oil when your changing the oil is strongly recommended. Some vehicles will simply not operate correctly as it consumes synthetic oils. If the motor oil has a hot viscosity that is not sufficiently high, the oil could start to break apart under extremely hot conditions and will not lubricate the components of the engine properly. This will eventually lead to burning oil. Over time, this can ultimately damage your engine due to excessive friction between metal components. If your motor oil has excessive thickness to consume for their range of conditions, your fuel mileage will possibly suffer. This is because the thickness of oil brings up resistance when inspecting parts such as pistons. When giving the right protection to your engine, it will be more costly if taking more trips to the gas station. If you are using motor oil with a viscosity that is excessively thin for these types of conditions, you may hear your engine produce a ticking noise. Your engine will usually produce the loudest noise after starting and intemperately decreasing after driving about for certain duration. This takes place if engine oil has a proper weight that necessitates for a negative job of coating and lubricating all engine components. You can hear metal components such as valves and valve lifters collide with other metal components. A brief change to a variation of oil thickness could solve the error.
5. Intake Valve - Ticking or popping sounds are the most common kinds of sounds you will notice when you are experiencing issues with your valves. You will frequently hear this ticking sound before you see another issue. This sound will get louder and quicker when the engine accelerates. It normally displays a location of the valve train components that either wears out or doesn’t align, or that your engine is not given sufficient lubrication. A majority of vehicles consist of hydraulic lifters, and these lifters require continuous lubrication and pressure conserved at an exact level. If the pressure is rather off the chart, it brings up the reaction or inconsistent motion inside the valve train. Blue smoke is a common sign of an utmost engine problem and you should never condemn these signs. In addition, blue smoke is not particularly an outcome of valve issues, as it is among the most common specifications, even when mixed with ticking and popping sounds. When valve guides and seals wear out, this enables oil to enter into the combustion chamber and burn together with the fuel. Moreover, you will see that your oil levels continue to plummet, or you frequently have to add on more oil, and you have sealed all the leaks. Normally, the quantity of blue smoke you notice with the valve guide and seal failure is very slight and scarcely in view. If you are sputtering out a huge quantity of smoke, then you might be dealing with more extreme issues such as damaged or worn out piston rings. It is better to consult with a professional mechanic to check where the engine issue is located and whenever you are dealing with this kind of issue. Another indicator that you are encountering any valve issues is that you often see a decrease in engine power and performance. Valves are applicable to fit snugly into the seats and enable for a lot less space. If your valve guides and seals are transpiring to leak, oil can build up atop of the valve and result in a lack of seating or power and combustion. Burnt valves are another issue that results in power loss. A burnt valve is susceptible of losing material and even cause massive holes that are leaking gases and decrease compression. Many parts will result in burning valves, but among the most generic explanations is to disregard seals and guides that are leaking, or fail to repair other compression issues. You can repair these problems with a cooling system or EGR (exhaust gas re-circulation) problem, and you are most susceptible of burning all the valves. These instances should not be ignored, as they are related to the valve, and can get even worse and expensive down the way. Otherwise, it is easy to prevent this from happening ever again, or be detained with the correct engine conservation. Make sure your oil is changed on a regular basis, and repair any other engine problem without any delay.
6. Valve Timing Solenoid - Whenever an Engine Control Unit (ECU) regulates modern vehicles, almost all-individual components are monitored by the ECU. As individual components start to fail, the ECU will supply a particular trouble code that will allow a mechanic to utilize a scanner that simply checks if an error is increasing. When the code has entered the system, it will warn the driver by activating a certain zone warning light to illuminate. The Check Engine Light is the most common light that illuminates when it gets used, it is critical for a vehicle owner to deal with a professional mechanic to inspect the vehicle, using the proper diagnostic scan tool to download the code and find out the precise reference of the problem. Moreover, there are many individual codes of a VVT solenoid issue for every vehicle manufacturer. When the mechanic finally gets a hold of the correct information, they can start to resolve this specific problem. The VVT solenoid operates at top value, as the engine oil is clean, free of debris, or loses a certain amount of lubrication or thickness. When the engine oil gets clogged with dirt, debris or other outside matter, it eventually clogs up the passages by the solenoid to the VVT chain, as well as the gear. If you have failed to change your engine oil outside of a certain time frame, it might damage the VVT solenoid, the VVT chain, as well as the gear drive. To stop this occurrence from constantly getting worse, make sure your oil is changed as recommended by the vehicle manufacture. Regularly, the VVT system doesn’t succeed in actuating before the engine gets placed to a high RPM or is directed into a course of loading bearing settings, such as driving uphill. Whatsoever, if the VVT solenoid doesn’t succeed in operating, it is possible to conserve expending an addition of engine oil to the VVT gears. This will lead the engine to idle roughly, specifically the engine RPM will change when the system is activated. If you fail to continue inspecting this, then lead to more engine components to wear down earlier on. If your engine idles to an extent it gets rough, make sure to reach an experienced mechanic to inspect this issue right away. The motive of variable valve timing is to ensure the valves open and close at the correct timing to enhance engine performance and reduce fuel consumption. When the VVT solenoid doesn’t succeed to perform, the entire system can be compromised, which could result in an intake and exhaust valves to open and close at the improper timing. This normally causes the fuel economy to endure with a powerful reduction.

If you are eager to simply diagnose this trouble code, all you need to do is read these steps, which are described as follows:

• First step to correct the issue with this system for any malfunction is to research on the Technical Service Bulletins (TSB's) to specify the precise vehicle by year, model and engine.
• In some circumstances, you can save a whole lot more time and money if leading yourself into the right direction.
• Second step is correcting the engine oil setting and affirm it is maintained at the right level. Next step is to find out where all parts are related to the cylinder 1 deactivation intake valve control circuit and check for any evident physical damage. Referring to the specific vehicle, this circuit could intermix numerous parts that come with the deactivation solenoid, switches, defect signals and ECM. Perform a rigorous visual test to specify the related wiring for evident faults such as scraping, rubbing, bare wires, or burn spots. Next step is to check the connectors and connections for all security, damaged and corroded pins. This system comes with all wiring connectors and connections to all parts that include ECM. Sourcing to a particular reference of technical data for the vehicle makes sure the arrangement of the cylinder 1 deactivation/intake valve control circuit and affirms each part is intermixed within the circuit, which might come with a fuse or a fuse-able connection.

Advanced Steps - The advanced steps are vehicle specific and need the correct advanced equipment to operate consistently. These methods need a digital multi meter and the particular technical sources for the vehicle.

Voltage Checks - The sourced voltage and the accepted scales might differ based on the particular vehicle and the circuit arrangement. Certain tech data will come with troubleshooting charts and the correct patter to follow that will help you with a consistent diagnosis. If this system checks on a lack of power source or ground, progression inspecting might be needed to detect the durability of the wiring, connectors and other parts. Progression inspecting should always be operated when removing the power from the circuit and the regular readings for wiring and connections have to be a resistance of 0 ohms. Resistance or no progression is identified as a defective wiring that is open, shorted or corroded and must be adjusted or swapped.
