Condition
Some customers may comment on the MIL/check engine light on, possibly resulting in reduced engine power.
Upon further investigation, the technician may find DTC P2101 and/or P2135 set as current or in history.
Cause
Based on feedback provided by dealer technicians, engineering was able to determine that the cause of this condition may be due to poor terminal crimps in the engine wiring harness.
Correction
Perform one of the following recommendations:
- If DTC P2101 only sets, follow published diagnostics in SI and repair as instructed.
- If DTC P2135 only sets, replace the engine wiring harness.
- If DTCs P2101 and P2135 set together, follow published diagnostics in SI for P2101 and repair as instructed. For P2135, replace the engine wiring harness.
