P2661 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P2661 can be described as B Rocker Arm Actuator System Performance/Stuck Off Bank. 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.

Error code P2661 flashing? The P2661 trouble code would start appearing when there is an electrical issue in the rocker arm actuator control circuit for the exhaust camshaft in bank 2 of the engine.

What causes this problem with the B Rocker Arm Actuator System Performance/Stuck Off Bank?

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

1. Fuel Injector - If there is a leakage in the fuel injectors, then it might cause a rise in the fuel consumption, fuel odours around the vehicle and hard starting. You can always rely on us as we have the best auto parts for our customers.
2. Electronic Control Unit – ECU monitors the temperature differences in the boost converter with the help of the temperature sensors to prevent the converter from overheating and malfunctioning. Thus, replace faulty ECU immediately.
3. Fuel Delivery System Parts - If you want your car engine to run perfectly, then you will need an efficient fuel system for that. The parts of fuel system are fuel tank, filter, pump, tank and injector or carburetor. If there is a failure in any of these components, then it would lead to faults in the entire fuel system. We have top notch fuel delivery system parts for our dear customers.
4. Engine Control Module - ECM failures and faults can be very difficult to find and resolve as these are very rare and might require a complete reprogramming of the system to avoid wrong codes from getting stored in the system, leading to misdiagnosis. Replace it now!
5. Powertrain Control Module - Faulty PCM can disrupt the normal functioning of the vehicle by affecting the transmission system and the fuel delivery system. This will cause the system to store wrong OBD error and thus can lead to misdiagnosis.
6. Diagnostic Tool - In order to be that DIY guy, you need few diagnostic tools to get your car problems pointed out easily. Our diagnostic tools collection will come in handy to do so, so why not have a look?

Do you wish to diagnose P2661 error code easily? 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 P2661 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 P2661 Code

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