DTC Troubleshooting: P15B0, P15C0
DTC P15B0: CKP Sensor Signal Malfunction
DTC P15C0: CKP Sensor Signal Intermittent Interruption
NOTE:
Before you troubleshoot, record all freeze data and any on-board snapshots, and review the general troubleshooting information.
If PGM-FI system's DTC P0335 and/or P0339 is stored at the same time as DTC P15B0 and/or P15C0, troubleshoot P0335 and/or P0339 first, then recheck for P15B0 and/or P15C0.
