Where does the oxygen sensor plug in?
O2 sensors look like a plug sticking out of the exhaust system. They are normally positioned either in the catalytic converter or before and after it (with two separate sensors). Unplug the electrical wiring from the sensor. Squeeze the release tab and pull the plug out from the sensor housing.
Where is the rear O2 sensor located?
The rear oxygen sensor is located in the front section of the rear catalytic converter. On the 2.2L engine the front (A/F) oxygen sensor is located in the front section of the front catalytic converter. The rear oxygen sensor is located in the rear section of the rear catalytic converter.
Where are the oxygen sensors located on the engine?
