DTC Troubleshooting: P15BE, P15BF
DTC P15BE: CMP Sensor Signal Malfunction
DTC P15BF: CMP 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 P0365 and/or P0369 is stored at the same time as DTC P15BE and/or P15BF, troubleshoot P0365 and/or P0369 first, then recheck for P15BE and/or P15BF.
