Crankshaft Variation Learn Procedure: Introduction
WARNING: This page is about a different car, the 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
The crankshaft position system variation compensating values are stored in the PCM non-volatile memory after a learn procedure has been performed. If the actual crankshaft position system variation is not within the crankshaft position system variation compensating values stored in the powertrain control module (PCM), DTC P0300 may set.
The crankshaft position system variation learn procedure should be performed if any of the following conditions are true:
- DTC P1336 is not set.
- The PCM has been replaced.
- The PCM has been reprogrammed.
- The engine has been replaced.
- The crankshaft has been replaced.
- The crankshaft position (CKP) sensor has been replaced.
