    Default Oxygen Sensor in 98 Ford Escort



    My O2 Sensor is failing in my 1998 Ford Escort. Is this a simple thing to
    change? Any tips in changing it?

    Any help will be appreciated.

    I see most of the parts stores around me carry Bosch. Will I get into
    trouble using a non ford part here? - John

    How do you know it is failing?

    A lot of people recommend using on OEM replacements.

    Are you sure it's the sensor? And if so, which one? (a '98 should have two,
    one upstream and one downstream of the catalytic converter). Oxygen sensors
    sometimes fail, but more often than not a 'lean' or 'rich' code from them
    just shows that they are doing their work and the problem is elsewhere.

    Most often the O2 sensor is working and is just cluing you in to some
    other problem, possibly a vacuum leak. Parts stores always tell their
    customers to replace their O2 sensors because then they buy one
    immediately. When that doesn't work, they suggest something else.
    It's their business. Find the real problem and then go buy that
    part. Don't shoot the messenger. Have the car scanned for codes and
    post them here, you'll get some real help and direction.

    I am glad my mechanic didn't change the O2 Sensors. Although, the car has
    160000 miles on it. AutoZone checked the code and found P0442, evaporative
    container. They had me replace the gas cap. If its not that I can work
    from there. I did find the code on the web in a TSB. They have summaries
    of the problem but not the solutions. I suppose I can call the dealer.

    Thanks for everyone's help. John

    An improper sealing fuel cap can certainly cause that code, as can fueling the
    vehicle with the engine running.
    It's also very common, on mid-late 90s Escorts, for the Canister Purge Valve or the
    Canister Purge Sensor to fail. So common that it is recommended to replace them both
    if one is found to be bad. The 2 parts came together in a kit from Ford as late as '02
    for sure. They may still be sold this way.

    They still are, for about $70 for the kit, which includes the 2 parts and
    the hard tubing
    that connects them both. However, the code for that evap problem is usually
    P1443.
    A P0442 is more likely a small leak in the gas tank, filler neck or gas cap.

    Thanks for the refresher Bob. I've been away since early 2001, many of those brain
    cells have gone to sleep. You're right, P1443 usually led to the Purge valve and/or
    sensor.
    P0442 was common if the gas cap was leaky, or there were other minor EVAP leaks.
