Camshaft Position Sensor: Description and Operation
Camshaft Position (CMP) Sensor and Signal
The camshaft position (CMP) sensor sends a CMP signal to the PCM. The PCM uses this signal as a "sync pulse" to trigger the injectors in the proper
sequence. The PCM uses the CMP signal to indicate the position of the #1 piston during its power stroke. This allows the PCM to calculate true
sequential fuel injection (SFI) mode of operation. If the PCM detects an incorrect CMP signal while the engine is running, DTC P0341 will set. If the
CMP signal is lost while the engine is running, the fuel injection system will shift to a calculated sequential fuel injection mode based on the last fuel
injection pulse, and the engine will continue to run. As long as the fault is present, the engine can be restarted. It will run in the calculated sequential
mode with a 1-in-6 chance of the injector sequence being correct. Refer to DTC P0341 for further information.
CMP Signal
The PCM uses this signal to determine the position of the number 1 piston during its power stroke, allowing the PCM to calculate true sequential
multiport fuel injection (SFI). Loss of this signal will set a DTC P0341.
If the CMP signal is lost while the engine is running, the fuel injection system will shift to a calculated sequential fuel injection based on the last fuel
injection pulse, and the engine will continue to run. The engine can be restarted and will run in the calculated sequential mode as long as the fault is
present, with a 1-in-6 chance of being correct.
