FAQ for Oxygen Sensor Repair
Q: What is the heater oxygen sensor installation procedure?
A:
Install the HO2S to the exhaust manifold and tighten the sensor to 42 Nm. Install the HO2S electrical connector retainer to the retainer clip. Next, install the fuel injector sight shield.

02/11/2022Q: What should be cautioned about the Silicon Contamination of Heated Oxygen Sensors (HO2S)?
A:
Contamination of the oxygen sensor can result from the use of an inappropriate RTV sealant (not oxygen sensor safe) or excessive engine coolant or oil consumption. Remove the HO2S and visually inspect the portion of the sensor exposed to the exhaust stream to check for contamination. If contaminated, the portion of the sensor exposed to the exhaust stream will have a white powdery coating.
