Crankshaft/Camshaft Sensor Circuit:

CIRCUIT DESCRIPTION
This DTC will determine if the distributor is installed incorrectly, or if there is a mechanical malfunction in the engine. DTC P1345 is a type "A" DTC.

DTC P1345 WILL SET WHEN
When engine is running, the cam sensor reference pulse is not detected at the correct relative position with crank pulse.

DTC P1345 WILL CLEAR WHEN
The VCM-A will turn the MIL "OFF" after three consecutive trips without a fault condition present. A history DTC will be cleared if no fault conditions have been detected for forty warm-up cycles [coolant temperature has risen 22°C (40°F) from start-up coolant temperature and engine coolant temperature exceeds 71°C (160°F) that same ignition cycle] or the Tech 1 clearing feature has been used.
