Error Code P264A: What It Means & What To Do?

<<See All OBD Codes

The trouble code P264A can be described as ‘A’ Rocker Arm Actuator Position Sensor Circuit Bank 1. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. This would also give rise to the illumination of the check engine light.

The powertrain control module (PCM) keeps the supply of oil in check within mechanically safe ranges. The engine depends on oil for a frictionless environment so that the engine components move at extremely rapid speeds without overheating. Without the lubrication, the internal engine components, such as rocker arms, will overheat and may scrape against their mating surface, instead of sliding.

The PCM uses sensors such as a rocker arm actuator, or oil pressure switch, to regulate the flow of oil to the engine. If the OBD code P264A is stored, it means the PCM has detected an abnormal feedback from the rocker arm actuator position sensor.

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

• Low or overfilled engine oil
• Inaccurate engine oil type
• There can be distorted 'A' Rocker Arm Actuator Sensor
• 'A' Rocker Arm Actuator Sensor harness is open or small
• 'A' Rocker Arm Actuator Sensor circuit might have inadequate electrical connection

1. Engine Control Module - There can be some engine performance issues due to faulty engine control module. If the ECM fails or has any problems it can lead to performance issues with the vehicle like misfires, hesitation, loss of power, and sometimes even decreased fuel economy.
2. Fuel Injector - Facing some issues in starting your vehicle? Poor idle issues? Failed emissions? These are all the symptoms of bad, faulty, leaking and clogged fuel injectors. It would be a good decision to replace your defective fuel injector with a new one online.
3. Powertrain Control Module - PCM stands for powertrain control module. It is a car part, a control unit which is utilized on motor vehicles. It is generally a combined control unit, consisting of the engine control unit (ECU) and the transmission control unit (TCU).
4. Electronic Control Unit - If your automobile's check engine light remains on constantly, and never goes off, there's a good chance that your vehicle has a damaged electronic control unit. There are a lot of reasons why a car's check engine light will remain on. The most common reason is a defective ECU.
5. Diagnostic Tools - It is always advisable to use the correct tools and equipment while resolving any OBD code issue as even small mistakes can lead to wrong diagnosis. Thus, always take help from a professional who has the knowledge and experience to such tools in an efficient manner. Buy new quality diagnostic tools from us today!
6. Camshaft Position Sensor - The mixture of air and fuel in the internal combustion engine requires a spark in order for the ignition to take place. In certain vehicles, the spark cannot be generated if there is a bad or faulty camshaft position sensor. If you cannot generate a spark, then you cannot start your engine. Thus, replace faulty sensor now!
7. Rocker Arm - If the rocker arm is faulty, it can affect the internal combustion system and the engine performance. Thus, replace it now!
8. Fuel Pressure Sensor - Sometimes the engine control unit senses a problem with the signal from the fuel pressure sensor. Then it may activate the check engine light to let you know there is some kind of problem that is related to the engine. Thus, check and replace faulty pressure sensor now!

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P264A here:

Common Symptoms

• Check engine light can start flashing up
• Reduced engine performance
• Smoke from the tailpipe
• Growth in the fuel consumption

Here are some ways with the help of which you will be able to correct the OBD Code P264A.

• You must add enough amount of engine oil
• Carefully adjust the faults in the oil control valve
• The camshaft sensors should be restored to working order
• Recondition the non-functioning circuits and connectors associated with the oil control valve
• Adjust the flawed PCM

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

• The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
• Then the trouble codes should be reset and then the vehicle should be started once again to see if the P264A error code exists. If the code is not returning, then it was erroneously triggered.
• If this error code returns, then the technician should check the engine oil levels as well as pressure.
• Then the connectors and circuits surrounding the oil control valve should be examined and then check the timing indicators for correct alignment.
• Carefully monitor the oil control valve and camshaft sensors.
• If any component is restored, then the error code should be reset before the examination continues.

Common Mistakes When Diagnosing The P264A Code

• The variable valve lift controller assembly might start failing
• Non observance of the powertrain control module
• Some issues with the car wiring
