Oxygen Sensor: Vehicle Damage Warnings
Excessive Force and Oxygen Sensor Notice
Excessive Force and Oxygen Sensor Notice
Notice: 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.
Oxygen Sensor Notice
Oxygen Sensor Notice
Notice: Handle the oxygen sensors carefully in order to prevent damage to the component. Keep the electrical connector and the exhaust inlet end free
of contaminants. Do not use cleaning solvents on the sensor. Do not drop or mishandle the sensor.
Silicon Contamination of Heated Oxygen Sensors Notice
Silicon Contamination of Heated Oxygen Sensors Notice
Notice: 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 in order to check for
contamination. If contaminated, the portion of the sensor exposed to the exhaust stream will have a white powdery coating. Silicon contamination causes
a high but false HO2S signal voltage (rich exhaust indication). The control module will then reduce the amount of fuel delivered to the engine, causing a
severe driveability problem. Eliminate the source of contamination before replacing the oxygen sensor.
