P0341 - Camshaft Position Sensor 'A' Circuit Range/Performance (Bank 1)

P0341 is set when the Engine Control Unit (ECU) detects that the signal from the Camshaft Position Sensor (CMP) is outside the expected range or is not properly synchronized with the Crankshaft Position Sensor (CKP). The sensor typically uses Hall-effect or inductive technology. The ECU relies on this signal to determine cylinder identification for ignition timing, sequential fuel injection, and Variable Valve Timing (VVT) control. If the correlation between the cam and crank signals deviates beyond a calibrated threshold (usually +/- 6 to 10 degrees), the code is stored. This can be caused by EMI (electromagnetic interference), incorrect sensor air gap, or mechanical timing issues like a stretched timing chain.
