DTC P0341: CMP Sensor Circuit Performance: Description
WARNING: This page is about a different car, the 2003 Pontiac Grand Prix, 2003 Chevrolet Malibu, and 2003 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.
During cranking, the Ignition Control Module (ICM) monitors the 7X Crankshaft Position (CKP) sensor signal. Once the engine starts the ICM determines spark synchronization, by the Camshaft Position (CMP) sensor pulses. The Powertrain Control Module (PCM) constantly monitors the number of pulses on the CMP signal circuit and compares the number of CMP pulses to the number of 24X reference pulses and the number of 3X reference pulses being received. If the PCM receives an incorrect number of pulses on the CMP signal circuit, DTC P0341 will set.
