The automobile fault code P2648 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour. Therefore, the total cost of diagnosing and fixing the P2648 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The P2648 code is related to the Rocker Arm Actuator circuit in the engine. The Engine Control Module (ECM) controls the oil hydraulic circuit through the Rocker Arm Actuator.

The Rocker Arm Actuator adjusts the engine’s valve timing through the variable valve timing (VVT) system.

The P2648 code is set by the ECM when the ‘A’ Rocker Arm Actuator circuit is not within factory specifications.

This code indicates a low circuit condition in the ‘A’ Rocker Arm Actuator Control Circuit of Bank 1.

What are the possible causes of the P2648 fault code?

If you see the engine light on or service engine soon warning light, it could be due to the P2648 fault code. This code can be caused by low or overfilled engine oil, incorrect engine oil type, faulty ‘A’ Rocker Arm Actuator, an open or shorted ‘A’ Rocker Arm Actuator harness, or a poor electrical connection in the ‘A’ 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 broken, bent, pushed out, or corroded connector pins.
