HO2S Inspection
1. Visually/physically inspect the HO2S for the following conditions:
- Ensure that the HO2S is securely installed.(Pigtail and wiring harness not making contact with the exhaust pipe)
- Check for corrosion on terminals and terminal tension (at the HO2S and at the PCM)
- Front HO2S for silicon contamination. This contamination will be indicated by a white powdery coating on the portion of the sensor exposed to the exhaust stream and this will result in a but false(high) voltage signal.
- Fuel, engine coolant or oil contamination.
- Use of improper sealant.
2. Was a problem found in any of the above areas?
