58X Reference PCM Input (Axiom & Rodeo 3.2L)

The Powertrain Control Module (PCM) uses 58X signal from Crankshaft Position (CKP) sensor to calculate engine RPM and crankshaft position at all engine speeds. PCM also uses pulses on this circuit to initiate injector pulses. If PCM does not receive pulses on this circuit, DTC P0337 will set. Engine will not start and run without 58X reference signal.
