Error Code P264E: What It Means & What To Do?

<<See All OBD Codes

Is your car engine misfiring? Do you notice smoke emitting from your car’s tailpipe? Is there a difference in the fuel consumption and the engine performance output? All these symptoms can be due to faulty rocker arm actuator sensor causing OBD code P264E to get stored in the system.

The rocker arm of an internal combustion engine changes radial movement into linear movement; this kind of device is properly called a reciprocating lever. It takes the spinning motion of the overhead camshaft and turns it into the up-and-down movement that opens and closes the valves. Because they are typically made of steel, rocker arms have a great deal of strength for their weight, and can therefore exert a great deal of leverage. When the position sensor for the rocker arm actuator for engine bank 1 doesn’t function properly, OBD code P264E gets stored in the powertrain control module (PCM).

What causes this problem with the ‘A’ Rocker Arm Actuator Position Sensor Circuit Intermittent/Erratic Bank 1?

• Issues related to low or overfilled engine oil
• Imprecise engine oil type
• Quirks in the 'A' Rocker Arm Actuator Sensor
• 'A' Rocker Arm Actuator Sensor harness might be unlocked
• 'A' Rocker Arm Actuator Sensor circuit bad electrical connection

1. Engine Control Module - The solenoid might cause a short in the engine control module because of corrosion in the solenoid or the wire running from the solenoid to the ECM harness.
2. Electronic Control Unit - The ECU power management control module keeps in check the hybrid battery charging functions. If the ECU is faulty, the battery pack will not be able to properly get charged and thus, the ECU might need replacement.
3. Powertrain Control Module - A trouble with the PCM would mean that it is unable to determine the right fuel mixture and would send the car engine either more or less fuel than it requires. Now when the engine gets more, the carbon emission would increase and fuel economy would drop. In case of the opposite, the engine will choke, stutter, and might start stalling sometimes.
4. Diagnostic Tool - Usually any OBD code problem requires deep insight into the problem and high grade tools in order to fix it properly. Thus, buy quality diagnostic tools form us!
5. Fuel Injector - Bad fuel injectors can cause starting issues, poor idles and affected performance. Thus, the replacements are in order. Buy new fuel injectors now!
6. Camshaft Position Sensor - If the camshaft position sensor goes bad, the set gear may lock in place. This means that the driver will have trouble shifting to another gear, although even might not be able to shift at all. Thus, replace it now!
7. Rocker Arm - One of the most noticeable symptoms will be noise coming from the drive train. You will need to visually inspect the rocker arms to see if they are sufficiently getting pushed by the pushrods. Replace it now!

We at Parts Avatar Canada care for our customers, and that’s why we will help you to diagnose P264E code by listing out some major symptoms. They are mentioned below as follows

Common Symptoms

• Appearance of the service engine soon light
• Degrading engine performance
• The fuel consumption might start increasing

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

• You must fix the defective rocker arm actuator
• Rehabilitate the defaults in the wiring and connectors
• The malfunctioning oil pump should be repaired or replaced as per the need
• The Oil control valve should be restored to working order
• It is necessary to perform proper service of the unsound oil pressure sensor

However, if you face any issue then we have stocked a wide range of best priced ECM, Rocker arm, Engine valve, Engine oil, PCM, VVT, Position Sensor 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:

Carefully examine the crankshaft and camshaft positions using electromagnetic sensors. Begin a proper diagnosis by making sure that all engine timing indicators are properly aligned. Check the test belt or chain deflection using manufacturer’s specifications. Next, test the VVT or VCT solenoids and circuitry if timing components prove to be properly aligned and in good working order. Check and replace faulty electrical wiring and connectors as they are more prone to fail than sensors, especially where oil or other corrosive fluids are present. Make use of an OBD-II scanner (or code reader), a digital volt/ohmmeter, and an oscilloscope to diagnose this error. Repair or replace damaged, disconnected, shorted, or corroded wiring, connectors, and components as necessary. Always retest the system after repairs are completed to ensure success. If all system wiring, connectors, and components (Including fuses) appear to be in normal working order, connect the scanner (or code reader) to the diagnostic connector and record all stored codes and freeze frame data. Inspect the PCM for any errors and reprogram it, if necessary.

Common Mistakes When Diagnosing The P264E Code

• Non-performance of the powertrain control module
• Failure in the variable valve lift controller assembly
• Issues related to the wiring
