Guide To P264C OBD Error Code Solutions

<<See All OBD Codes

The trouble code P264C can be elucidated as ‘A’ Rocker Arm Actuator Position Sensor Circuit Low Bank 1. If this error code would start appearing, then it would mean that there is an open circuit or a short which has been detected in the rocker arm actuator position sensor circuit for the engine bank 1.

The rocker arm actuator is an oil pressure switch which controls the flow of oil to critical upper engine cylinder head components. The rocker arm actuator is a unit consisting of oil passages governed by the ECM, where the passage operation alternates depending on the driving conditions, and each particular passage varies the oil pressure to the cylinder head. When the PCM is unable to detect the rocker arm position due to low voltage output from the sensor for engine bank 1, OBD code P264C gets set.

What causes this problem with the Rocker Arm Actuator Position Sensor Circuit Low Bank 1?

• Less or overfilled engine oil
• Wrong engine oil type
• Malfunctioning 'A' Rocker Arm Actuator Sensor
• 'A' Rocker Arm Actuator Sensor harness might be unlocked
• 'A' Rocker Arm Actuator Sensor circuit poor electrical connection

1. Engine Control Module - Is your car engine light still staying ON after resetting or your car engine is turning off for no reason? Then these are some common symptoms indicating that your car engine control module is defective.
2. Powertrain Control Module - The PCM works as the central computer system in an automobile’s mechanism. This auto part is in charge of all the constituents as well as the functions performed by them. Having such enormous importance in the operation of all the parts means that any defect in it will affect almost every aspect of a car.
3. Electronic Control Unit - The ECU is a major component of your car's onboard computer. It's used to regulate many systems and subsystems in your car's engine, drive train and other major components. Visit us to buy best quality ECU online.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

After verifying the P264C code with an OBD-II scanner, the mechanic should begin with a visual inspection of all electrical components. It should be connected to the onboard computer and then the data from the car should be gathered. This would help the mechanic to know which codes are existing and what problems would be at play in the automobile. After that he should reset the codes and then the vehicle should be taken out for a test drive. This would help them to see how the automobile is running and if the error code is returning, then they would have a better idea of what the issue might be. After that, they should start with the potential repairs.

Check for dead battery and damaged or corroded battery cables. If the engine cranks, it may also be due to faulty starter motor relay, clogged fuel injector and ignition system. Check and replace faulty components immediately.

Always clear the code and retest the vehicle to see if the code returns. If it does, keep continuing the diagnosis. Check for the faults in the PCM and repair and reprogram it to avoid any issues.

Common Mistakes When Diagnosing The P264C Code

• Powertrain control module might start failing
• Some issues related to the variable valve lift controller assembly
• Issues with the car wiring
