Here’s all you need to know about the OBD code P2650. The engine control module (ECM) undertakes the task of ordering the rocker arm actuator to monitor the oil hydraulic circuit. In order to adjust the engine’ valve timing, oil can be seen flowing through the rocker arm actuator to the variable valve timing system.

It is notable that in order to enhance the engine’ performance, fuel economy or emissions, the variable valve timing (VVT) system is utilized. The engine control module performs the function of regulating the rocker arm actuator circuit. The OBD-II error code P2650 is stored by the engine control module whenever the rocker arm actuator circuit fails to fall out of the manufacturers specifications.

What causes this problem with the Rocker Arm Actuator Control Circuit/Open Bank 1 ?

• Open circuits in the connections associated to the actuator or the actuator itself
• Open circuit signal from the B rocker arm actuator (identified by the engine control module)

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

• Firstly to begin with, the technician should scan the codes and record the code in the engine control module to view the freeze frame data for the code stored
• Then perform a thorough visual inspection of all the electrical components including the wiring and the connectors to the actuator to ensure its working in order
• Then the technician should perform the manufacturer’ pinpoint test on the B rocker arm actuator to check if the actuator has failed or it there re open or corroded wirings present in it

Common Mistakes When Diagnosing the P2650 Code

• Don’t want to take a chance of missing the error code? Well, we have listed here only for the convenience of our customers all the common mistakes that should be avoided while performing the procedure:
• Firstly, it is important to verify the open circuits in the actuator. Only then the actuator should be repaired or replaced (not before verification)
• A failure to clear the engine control module codes after that the system has been repaired or replaced
• Restoring the parts while the connector isn’t making contact or is broken
