The P2660 code is related to the ‘B’ Rocker Arm Actuator Control CircuitOpen Bank. 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 P2660 fault code?

If you see the engine light on or service engine soon warning light, it could be due to the P2660 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.

How can I visually inspect the wiring harness and connectors related to the ‘B’ Rocker Arm Actuator?

If your engine light is on due to a faulty ‘B’ Rocker Arm Actuator, you can visually inspect the related wiring harness and connectors to fix the issue. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. Also, make sure to check the possible causes listed above, including low or overfilled engine oil, incorrect engine oil type, and poor electrical connection in the ‘B’ Rocker Arm Actuator circuit.

What should I do if I find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection, it is important to address them immediately. These issues can cause poor electrical connections and lead to the engine light being on. To fix the problem, visually inspect the related wiring harness and connectors, and replace any damaged components or repair any broken, bent, pushed out, or corroded connector’s pins. This will ensure a proper electrical connection and help resolve the issue.
