NO
- This can be an intermittent fault caused by poor contact of the sensor and/or ECM connector. Or, ECM memory was not cleared after repair. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace the relevant component(s) as necessary, and go to "VERIFICATION OF VEHICLE REPAIR ".
