Possible causes

– Faulty Camshaft Position Sensor
– Camshaft Position Sensor harness is open or shorted
– Camshaft Position Sensor circuit poor electrical connection
– Faulty starter motor
– Starting system circuit
– Dead (Weak) battery

Tech notes

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.

Here is a flow chart from Honda to help diagnose the P0341 code problem: Honda Flow Chart Diagnose P0410 code

When is the code detected?

The camshaft position sensor signal sent to the Engine Control Module(ECM) during the first few seconds of engine cranking is out of range.

Symptoms

– Engine Light ON (or Service Engine Soon Warning Light)
– Possible lack/loss of power
– Engine may stall while driving

P0341 ACURA Description

The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Engine Control Module(ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of camshaft (intake) to identify a particular cylinder. The camshaft position sensor senses the piston position. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor.
When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change.
When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.
