What does p2647 mean in engine control module?
P2647 Meaning The Engine Control Module (ECM) commands the Rocker Arm Actuator to control the oil hydraulic circuit. Oil flows through the Rocker Arm Actuator to 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.

What is the OBD code for the rocker arm?
If the PCM does not receive the correct voltage signal back from the rocker arm oil pressure switch, it may set code P2646. The “A” in this OBD code’s definition indicates the intake camshaft.
What is the p2646 code for an engine?
Code P2646 is not a very common code since most vehicles do not have actuators for the rocker arms of the engines they manufacture.
Why do I keep getting a p0646 code on my car?
Although the ‘A’ rocker arm actuator will usually be the problem (and will need to be replaced), this is not always the case. Often, the culprit will be the oil itself (low oil level, inadequate oil pressure or viscosity), but mechanics will replace components in error, causing the P0646 code to return.
What are the possible causes of Honda p2646?
