Axiom 4WD V6-3.5L (2004)
Crankshaft Position Sensor: Description and Operation
General Description (ECM and Sensors)
58X Reference ECM Input
The engine control module (ECM) uses this signal from the crankshaft position (CKP) sensor to calculate engine RPM and crankshaft position at all
engine speeds. The ECM also uses the pulses on this circuit to initiate injector pulses. If the ECM receives no pulses on this circuit, DTC P0337 will set.
The engine will not start and run without using the 58X reference signal.
Crankcase Position (CKP) Sensor
The crankshaft position (CKP) sensor provides a signal used by the engine control module (ECM) to calculate the ignition sequence. The CKP sensor
initiates the 58X reference pulses which the ECM uses to calculate RPM and crankshaft position.
Refer to Electronic Ignition System section for additional information.
