The automobile fault code P2645 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 P2645 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 P2645 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 code is triggered when the ‘A’ Rocker Arm Actuator circuit in Bank 1 is not within factory specifications.

This code can affect the engine’s performance, fuel economy, and emissions.

What are the possible causes of the P2645 fault code?

If you see the engine light on or service engine soon warning light, it could be due to the P2645 fault code. This code can be caused by low or overfilled engine oil, incorrect engine oil type, faulty ‘A’ Rocker Arm Actuator, ‘A’ Rocker Arm Actuator harness being open or shorted, or poor electrical connection in the ‘A’ Rocker Arm Actuator circuit. To fix this issue, you should 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’s pins.

How can I fix the P2645 fault code?

If you’re experiencing the P2645 fault code, indicated by the engine light or service engine soon warning light, there are a few possible causes to consider. These include low or overfilled engine oil, incorrect engine oil type, a faulty ‘A’ Rocker Arm Actuator, or an open or shorted ‘A’ Rocker Arm Actuator harness. To fix the issue, visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

Is it safe to continue driving with the engine light on due to the P2645 fault code?
