[SOLVED] P2650 Code: Fixing Rocker Arm Control Circuit For Optimal Performance

The P2650 fault code in automobiles refers to a problem with the ‘B’ Rocker Arm Actuator circuit. The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light. The cause of this issue could be low or overfilled engine oil, incorrect engine oil type, faulty ‘B’ Rocker Arm Actuator, or a poor electrical connection in the circuit.

The repair importance is high as it can lead to engine damage if left unaddressed.

The repair difficulty is moderate, and the repair time is estimated at 1.0 hour.

To fix the issue, one should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops. Therefore, the total cost of fixing the P2650 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P2650 code refers to the ‘B’ Rocker Arm Actuator Control CircuitOpen Bank 1. The Engine Control Module (ECM) commands the Rocker Arm Actuator to control the oil hydraulic circuit. The Rocker Arm Actuator controls the variable valve timing system to adjust the engine’s valve timing.

The variable valve timing (VVT) system is used to improve engine’s performance, fuel economy or emissions.

The ECM monitors the Rocker Arm Actuator circuit and sets the OBDII when the ‘B’ Rocker Arm Actuator circuit is out of factory specifications.

What are the possible causes of the P2650 fault code?

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2650 fault code. This code can be caused by low or overfilled engine oil, incorrect engine oil type, faulty ‘B’ Rocker Arm Actuator, ‘B’ Rocker Arm Actuator harness being open or shorted, or a poor electrical connection in the ‘B’ Rocker Arm Actuator circuit. To fix this issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or connector pins that are broken, bent, pushed out, or corroded.
