Error Code P3453: What It Means & What To Do?

<<See All OBD Codes

Are you looking for information with respect to P3456 error code? Is the cylinder deactivation solenoid faulty? Keep reading further. To meet fuel and emission standards, most manufacturers will prefer to use cylinder deactivation system. The PCM will restrict the specific cylinders when more power is not necessary from the engine like idling or cruising on the highway. The error code will be set when the exhaust valve for cylinder #7 does not turn on or off when needed and the P3453 error gets stored

The cylinder 7 exhaust valve control circuit’s purpose is to turn off the exhaust valve to allow the cylinder deactivation feature, so that fuel economy can be spontaneous when the operation is light or idle on the highway. The 4 or 8 cylinder modes is correctly monitored by the ECM which deactivates 4 engine cylinders. This is perfectly done by including variable valve timing solenoids which turn on and off the exhaust valves. This error refers to the 7 cylinder and other cylinders will be identified by engine configuration and firing orders. The cylinder deactivation will be restricted to 10 minutes in V4 mode and comebacks to V8 mode in 1 minute. The 7 is placed on or near the exhaust manifold in the vicinity of the cylinder depending on the particular configuration of the vehicle

What causes this problem with the Cylinder 7 Exhaust Valve Control Circuit/Open?

• The cylinder deactivation solenoid might be defective.
• There might be an opening in the cylinder deactivation solenoid or the circuit might be shorted.
• The electrical connection of the cylinder deactivation solenoid circuit might appear to be weak.
• Constrained oil passage.
• Minimum oil pressure.

1. Engine Control Module - Conditions of misfire shows that your ECM is faulty. Fix it as soon as possible to avoid the P3453 error in your vehicle by getting a new ECM from PartsAvatar.
2. Powertrain Control Module - Overheating of the PCM can likely damage your PCM. Change it quickly by getting a new PCM from PartsAvatar.
3. Intake Valve - The intake valve has to function properly to avoid the P3453 error code. If it’s defective, replace them as soon as possible.
4. Exhaust Valve - Changing the damaged exhaust valve is always the best solution as it can cause the engine to misfire. Get the right replacement from PartsAvatar at affordable prices.
5. Oil Pressure Gauge - If you want to avoid the P3453 error code, then the defective oil pressure gauge has to be replaced instantly. You will find trouble while starting the car if the exhaust valve is defective. Replacing it quickly can help you to get rid of this error. 
6. Valve Timing Solenoid - Flashing of the check engine light is a sign of defective valve timing solenoid. Replacing it can avoid further troubles

Willing to know some common symptoms of OBD Code P3453? Your wish is our demand. Have a look at them below:

Common Symptoms

• Possible symptoms of a misfire.
• You might find the engine light or else the warning light of the service engine turned on.
• Performance by the engine is poor.
• You will find the consumption of fuel to be more.

We have listed out so ways which would help you to correct the occurrence of OBD Code P3453. They are mentioned here as follows:

• Filter and oil replacement.
• Faulty deactivation solenoid needs repair.
• Clearing tracks of the oil passage.
• Brushing the connectors which have corrosion.
• Fixing the wires.
• Replacing defective PCM.

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of ECM, PCM, intake valve, exhaust valve, oil pressure gauge, valve timing solenoid, exhaust manifold and many more. Now all your problems would vanish within no time.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P3453 code to be stored:

• Before you start the troubleshooting procedure, check for the correct Technical Service Bulletins (TSB's) which is specific for your vehicle by year, model and transmission.
• It can actually help you in saving time in the long run by guiding you in the right path.
• Secondly, you must inspect the engine oil condition and ensure it is serviced to the right level. Identify all components connected with the cylinder 7 exhaust valve control circuit and inspect for any defects.
• There might be several components included depending on the specific vehicle which includes the variable valve timing solenoid, switches, fault indicators, and the ECM.
• Now, perform a careful inspection of the wires for damages like scraping, rubbing, or burn spots.
• Also, you have to visually check the connectors and its connections for protection, erosion and damaged pins which include the wires, connected to various parts and the ECM.
• Always refer the tech data of the vehicle to check the alignment of cylinder 1 exhaust valve control circuit and make sure that every part is included within the circuit which also contains the fuse or a fuse-able link in certain applications.

Advanced Steps

• The advanced step for each and every vehicle is specific and it needs suitable tools to accomplish diagnosis correctly.
• The process will need a digital multimeter and certain technical references for your vehicle.

Voltage checks

• Based on the specific vehicle and configuration of the circuit, both the reference voltage and acceptable range will change.
• Troubleshooting charts and the appropriate sequence are included in the specific technical data to help with the proper diagnostic procedure.
• Continuity test has to be done to check the integrity of the wires, connectors and other connections if there is no power source or ground found in the process.
• Carry out the continuity test by removing power from the circuit and 0-ohms resistance must be set as normal reading for wires and connectors.
• The faulty wires which are open, shorted or eroded must be replaced or fixed if there is no resistance or continuity. 

Common mistakes when diagnosing the P3453 code

• Electrical wires might cause some issues
• Failure of the PCM.
• Less engine oil level.
• Variable valve timing solenoid might be damaged.
