oxygen sensors locations

2 Answers


The V6 has two O2 sensors. The upper one provides feedback to the ECU for fuel trim. It's in the exhaust header between the engine and the cat converter. The second sensor is downstream of the converter and monitors the condition of the converter.

This car is pre1996 no downstream. Just one upstream with a single purple wire going to it.
