Code P0341 Acura Description

The OBD-II trouble code P0341 for Acura vehicles indicates that the camshaft position sensor has detected incorrect phase detection. The camshaft position sensor is a crucial component that monitors the position of the camshaft in relation to the crankshaft. This information is vital for the engine control module (ECM) to determine the correct timing for fuel injection and ignition. When the camshaft position sensor fails to detect the correct phase, it can lead to a variety of performance issues and potentially cause long-term damage to the engine.

Tech Notes for P0341 Acura

A damaged or stretched cam chain, resulting from infrequent oil changes, can cause the MIL to come on with DTC P0341 (CMP sensor A and CKP sensor incorrect phase detected). Old oil causes the cam chain to wear quickly. As a result, it stretches beyond the point where the cam chain auto-tensioner can keep up.

That extra chain slack causes the valve timing control (VTC) actuator and the exhaust camshaft sprocket to lag behind, and you wind up with DTC P0341.
