Guide To P3455 OBD Error Code Solutions

<<See All OBD Codes

Is the hydraulic passage blocked? Then there is a chance that the P3455 error is stored in the vehicle. Cylinder deactivation system will be used by many manufacturers in order to meet the fuel and emission standards. The system helps the ECM to restrict selected cylinders when additional power is not required from engine during situations like engine idle or cruising on the highway. If the exhaust valve for cylinder #7 does not turn on or off as needed, the PCM will identify it and the P3455 error will be stored.

Turning off the exhaust cylinder to permit cylinder deactivation feature is the sole purpose of cylinder 7 exhaust valve control circuit. This can raise fuel economy when the operation appears light like idle condition on the highway. The 4 or 8 cylinder mode is properly looked after by the ECM which restricts 4 of the engine cylinders. The process gets fulfilled by including variable valve timing solenoid which turns the exhaust gas on or off. This code specifies the #7 cylinder and the remaining of the 3 cylinders will be identified by the cylinders engine configuration and firing orders. The cylinder deactivation will be delimited to 10 minutes in V4 mode by the ECM and comes back again for 1 minute in V8 mode. Either near the exhaust or on the vicinity of the cylinder depending on the specific configuration of the vehicle, the #7 cylinder variable valve timing solenoid is mounted.

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

• The cylinder deactivation solenoid might seem to be defective.
• You might find an opening in the cylinder deactivation solenoid harness or the circuit might be shorted.
• The electrical connection might be poor in the cylinder deactivation solenoid.
• Oil passage might be limited.
• Limited oil pressure.

1. Engine Control Module - Is the performance of the engine very poor? Does your engine keep stalling very often? Then the ECM might be faulty which needs replacement as soon as possible.
2. Powertrain Control Module - The PCM regulates important functions of the vehicle as well as it has a direct impact on how well your vehicle performs. Fixing your faulty powertrain control module (PCM) will help your engine to run smoothly.
3. Intake Valve - Inspect the intake valve if it is damaged or corroded. If they are found to be defective replace them immediately.
4. Exhaust Valve - Excessive smoke from the exhaust valve is an indication of a damaged exhaust valve. Change it as soon as possible or get a new one from PartsAvatar at best prices.
5. Oil Pressure Gauge - As a very rare case, a broken oil pressure gauge can help the P3455 error code to be stored. Change the faulty component as soon as possible.
6. Valve Timing Solenoid - Rough engine idle is an indication of damaged valve timing solenoid. A replacement has to be done as soon as possible.

We at Parts Avatar Canada care for our customers, and that’s why we will help you to diagnose P3455 code by listing out some major symptoms. They are mentioned below as follows

Common Symptoms

• High fuel consumption.
• Possible symptoms of a misfire.
• Blinking of the engine light as well as the warning light of the service engine.
• Reduced engine performance.

Learn the ways with which you can correct this trouble code:

• The faulty wires must be changed.
• Changing the damaged deactivation solenoid.
• The oil passage has to be free from blockages.
• Clearing off the corrosion from the connectors.
• ECM has to be flashed or fixed.

However, if you face any issue then we have stocked a wide range of best priced ECM, PCM, intake valve, exhaust valve, oil pressure gauge, valve timing solenoid, exhaust manifold and more to help you out in fixing your car.

Here are some steps which you should follow in order to diagnose this fault code P3455:

• You can initially begin with a troubleshoot method and examine for the correct Technical Service Bulletins that is precisely designed for your vehicle by year, model and transmission.
• This can help you in the long run by saving time as it guides you down the right path.
• Locate the component which is linked with the cylinder 7 exhaust valve control circuit and see for any damages and this will be your second step.
• Depending on your vehicle, the circuit may include other components such as variable valve timing solenoid, switches, fault indicators, and the ECM.
• Check for injuries like scraping, rubbing, or burn spots by visually inspecting these elements as well as the connectors and its connections to ensure safety.
• Connectors must be checked for erosion, defective pins, and security.
• The ECM must be inspected along with the wiring connections and the components.
• Look at the specific tech data of the vehicle and see for the configuration of the cylinder 1 exhaust valve control circuit and approve that every part is included in the circuit which may contain the fuse or a fuse-able link in some applications.

Advanced Steps

• Each and every vehicle have their own procedure as they are specific and you have to use proper diagnostic tools for the process.
• In order to start the process, you have to use a digital multimeter and appropriate technical references.

Voltage check

• The permitted range and reference voltage might vary based on the specific vehicle and configuration of the circuit.
• The troubleshooting charts and the suitable sequence which is included in the specific technical data can help in the correct diagnostic process.
• In this procedure, if there is no power source or ground, then the integrity of the wires, connectors, and other components have to be performed by carrying out a continuity test.
• While doing the continuity test, make sure to remove the power from the circuit and 0-ohms resistance must be set as normal readings for wires and connections.
• No continuity or resistance is a sign of damaged wires that might be open, eroded or shorted and needs a quick replacement.

Common mistakes when diagnosing the P3455 code

• Damaged PCM.
• An issue might arise due to faulty wires.
• Low-level engine oil.
• Malfunctioning variable valve timing solenoid
