    Q:
    What are the steps to replace the upstream oxygen sensor in the 2007 Mercury Mariner? Posted by Customer
    A:
    1. Disconnect the negative battery terminal. 2. Remove the exhaust manifold heat shield. 3. Disconnect the upstream oxygen sensor electrical connector. 4. Unscrew the upstream oxygen sensor using an oxygen sensor socket. 5. Apply anti-seize compound if reinstalling the old sensor. 6. Install the sensor and tighten it to the specified torque. 7. Reconnect the battery and allow the PCM to relearn its idle and fuel trim strategy.

    Q:
    Why is the oxygen sensor important for the PCM for the 2001 Ford Escape? Posted by Customer
    A:
    Without the oxygen sensor, the PCM would be unable to correct the injector on-time, which determines the air/fuel ratio needed to maintain the "perfect" (stoichiometric) air/fuel ratio of 14.7:1 that the catalyst requires for optimal operation.
