Record all DTCs, DTC state and freeze frame data. Is the DTC State "Present?"
NOTE:
- History (Not Present) state: the DTC set but has been cleared.
- Present state: the DTC is active at present time.
YES
- Go to next procedure.
NO
- Fault can be intermittent, caused by poor connection in sensor harness. Or, ECM memory was not cleared after repair. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair " procedure.
