Good
- Fault is intermittent caused by poor contact in the sensor's and/or ECM's connector or was repaired and ECM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "VERIFICATION OF REPAIR " procedure.
No Good
- If no problems were found with the circuits or connectors, replace the A/C control module and go to "VERIFICATION OF REPAIR " procedure.
