DTC P1345: Crankshaft/Camshaft Position Sensor Correlation: Description

WARNING: This page is about a different car, the 2002 Oldsmobile Bravada, 2002 GMC Envoy XL, 2002 GMC Envoy, and 2002 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.

The Powertrain Control Module (PCM) uses the crankshaft sensor and the camshaft sensor information to monitor the correlation between the crankshaft and camshaft positions. This Diagnostic Trouble Code (DTC) will set if the deviation between the crankshaft and camshaft exceeds a calibrated amount.
