Upstream O2 sensor V70-XC70 1999

posted by  someone claiming to be ravens on  Fri May 9 08:59 CST 2014 [RELATED]

Good day all, installed new upstream O2 sensor, CEL cleared, but came back on a few days later. Any ideas as to way? Do I need to have a OBD scanner to clear the code. Thanks!

    If you know what the code is, disconnecting the battery will erase the code. But, you should let a code reader do that for you.

    If you have the same O2 error code, look for an exhaust leak. Or you used a non standard O2 sensor that is not sensitive enough for the Volvo computer?
