P264D - OBD Trouble Code

<<See All OBD Codes

The trouble code P264D can be explained as ‘A’ Rocker Arm Actuator Position Sensor Circuit High 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. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

If the engine control module would detect a variation in the voltage coming from the A rocker arm actuator position sensor that is outside the parameters set by the automobile manufacturer, then it would store the P264D error code. This would also give rise to the illumination of the check engine light.

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

• Low or stuffed engine oil
• Inexact engine oil type
• Some issues related to the 'A' Rocker Arm Actuator Sensor
• Unlocked 'A' Rocker Arm Actuator Sensor harness
• Unsatisfactory electrical connection in the 'A' Rocker Arm Actuator Sensor circuit

1. Engine Control Module - Dead cells in batteries can cause a failure in the engine control module. Many times a battery is left in the rig long after a cell has died. This would affect the grounding in the car battery.
2. Powertrain Control Module - If there are some faults in the PCM, then it may throw off the timing and fuel settings of the engine, which can negatively affect the performance. A flawed PCM may cause the vehicle to experience a reduction in fuel efficiency, power as well as acceleration.
3. Electronic Control Unit - Do you know that the poor performance or unexplained drops in fuel economy or efficiency are often associated to onboard car computer problems, or defective ECU issues?
4. Diagnostic Tools - Use factory grade diagnostic tools to resolve OBD code P264D error. Buy new diagnostic tools and equipment for us.
5. Fuel Injector - The fuel injectors are an important component of the fuel delivery system that helps in proper utilization of the fuel entering the engine. This not only helps in taking care of the air to fuel ratio in the engine, helping the combustion process but also enhances the performance. Thus, replace faulty injector now!
6. Rocker Arm - The function of the rocker arms is to assist the pushrods in opening and closing the exhaust valve and intake value. This helps in proper combustion process and adequate power output from the engine. Thus, replace the faulty rocker arm now!

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P264D code by mentioning some major symptoms below:

Common Symptoms

• Check engine light might come into signal
• Low engine performance output
• The overall fuel consumption might start rising

Have a look at some ways with which you can correct the P264D code:

• You must fix the defective oil pump
• It is essential to restore the flawed oil control valve
• Repair or replace the quirky rocker arm actuator
• Rehabilitate the defaults in the oil pressure sensor
• Adjust the flawed wiring and connectors

Don’t get tensed if you are still facing any of these issues as we care for our customers and that’s why we offer a good range of ECM, Rocker arm, Engine’s valve, Engine oil, PCM, VVT, Position Sensor and a lot more. We are sure that now all your issues would be resolved.

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

• Make use of a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• Carefully inspect for every stored code and freeze frame data as it can help down the way for further diagnosis process.
• The vehicle’s computer should be inspected with a scanner in order to find out whether there are other accompanying codes, and whether they return after being cleared and then the vehicle should be taken out for a test drive.
• Examine the oil level and pressure.
• The oil pressure sensor and rocker arm actuator screens should be visually inspected.
• Carefully examine the wiring and connections involved in the oil pressure sensor and rocker arm actuator.
• The circuitry with a voltmeter should be tested and if the position sensor if faulty, it must be replaced immediately.
• Also inspect the PCM for any errors which may lead to wrong codes getting stored in the system and repair and reprogram the system immediately.

Common Mistakes When Diagnosing The P264D Code

• Malfunctioning powertrain control module
• There can be a failure in the rocker arm actuator position sensor
• Wiring and connector problems
