P0315 - Crankshaft Position System Variation Not Learned
- Crankshaft Position (CKP) sensor harness is open or shorted
- Crankshaft Position (CKP) sensor circuit poor electrical connection
- Damaged crankshaft pulse wheel teeth
- Engine fails to start
- Engine runs rough
The Crankshaft Position (CKP) sensor signal is monitored by the Engine Control Module (ECM) for errors. The P0315 code is set when ECM is unable to learn and correct for mechanical inaccuracies in crankshaft pulse wheel tooth spacing.
Any information is appreciated. Thanks
