    Heated 02 seņor light on 02 nissan altima
    The light is coming on for an 02 Nissan Altima. Changed both 02 sensors but still getting light. Saying closed loop. Any ideas. Thanks

    After you changed the oxygen sensors, did you use a code reader or scan tool to reset the ECM? Did you contaminate the pigtail connectors? This link may help:

    No nothing Like that pulled it out and hooked it strait up. Then used scanner to reset light. Now light coming back on. Same code.

    Did you install Denso sensors or generic Bosch?
