32020, code 401 front o2sensor
Posted by eclipse_99rs, Sep-06-02 03:25 AM
i was wondering if anyone knows how to find out if the o2 sensor is bad or how to fix it if its just a bad connection. And could it just be loose? I had to disconnect it to put my bosal catback on thats when the service engine soon light came on.

They are somewhat fragile. Its probably not working, just replace it. The more you mod the more you will go through o2 sensors.
