zrothauser Posted August 7, 2009 Report Share Posted August 7, 2009 My service engine light came on, and I got error code 13, Oxygen Sensor circuit open. I had the oxygen sensor replaced, and the light still comes on. Has anyone dealt with this error code? Quote Link to comment Share on other sites More sharing options...

BXX Posted August 7, 2009 Report Share Posted August 7, 2009 year/make/model/engine would be helpful. And brand of O2 sensor that was installed and how many miles were put on it.. Quote Link to comment Share on other sites More sharing options...
zrothauser Posted August 7, 2009 Author Report Share Posted August 7, 2009 It's a 93 CS 3.1L. I'm not sure how many miles the old 02 sensor had, at least 7000. But the new one, a Bosch, gave the error code the first time I drove it for more than 5 minutes. Quote Link to comment Share on other sites More sharing options...
Crazy K Posted August 10, 2009 Report Share Posted August 10, 2009 i'm the mech. the old sensor looked like new when pulled. it was a Bosch. the new sensor is a bosch as well. the code is still triggering. Quote Link to comment Share on other sites More sharing options...
mfewtrail Posted August 10, 2009 Report Share Posted August 10, 2009 Since you've had two separate o2's with the same issue, it's probably a wiring problem. Start tracing the o2 wiring circuit. Quote Link to comment Share on other sites More sharing options...
