Circuit Description
WARNING: This page is about a different car, the 2000 Isuzu Hombre. However, it is still accessible from the selected car via links, so may be relevant.
Powertrain Control Module (PCM) supplies battery power and ground to Crankshaft Position (CKP) sensor. CKP sensor sends a reference signal to PCM 7 times per revolution to indicate crankshaft position and engine speed. The seventh pulse is the sync pulse and is used for crankshaft position reference. PCM calculates when to pulse ignition coils based on these signals.
Conditions for setting this DTC are:
- DTC P0341 not set.
- 7x resync counter greater than 15 counts within 4 minutes and 15 seconds.
