DTC P0341: Camshaft Position Sensor Performance: Description
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2002 Pontiac Grand Prix, 2002 Pontiac Bonneville, 2002 Chevrolet Monte Carlo, 2002 Chevrolet Impala, and 2002 Buick Regal. However, it is still accessible from the selected car via links, so may be relevant.
Camshaft Position (CMP) sensor is a Hall-Effect type sensor. Sensor produces one signal for each revolution of camshaft to control sequential fuel injection. There are no direct circuits to Powertrain Control Module (PCM). All circuits are between CMP and Ignition Control Module (ICM). These circuits are CMP signal circuit, 12-volt reference circuit, and low reference circuit. PCM compares CMP sensor signal to number of 3X, low-resolution, engine speed signals generated by ICM. Normal ratio of 3X signals is 6 to 1. DTC sets when PCM receives an incorrect number of CMP sensor signals.
