FAQ for Oxygen Sensor Repair
Q: What should be noted for the Excessive Force and Oxygen Sensor?
A:
The oxygen sensor may be difficult to remove when the engine temperature is below 48°C (120°F). Excessive force may damage threads in the exhaust manifold or the exhaust pipe.

A:
You should not apply contact cleaner or other materials to the sensor or vehicle harness connectors, not damage the sensor pigtail and harness wires in such a way that the wires inside are exposed, and ensure the sensor or vehicle lead wires are not bent sharply or kinked, not remove or defeat the oxygen sensor ground wire and then ensure that the peripheral seal remains intact on the vehicle harness connector.

02/11/2022 Q: What should be done for the silicon contamination of heated oxygen sensors?
A:
You should remove the HO2S and visually inspect the portion of the sensor exposed to the exhaust stream to check for contamination. Then your control module will then reduce the amount of fuel delivered to the engine, causing a severe drivability problem, and then you can eliminate the source of contamination before replacing the oxygen sensor.
