Can't get the check engine light off. Bad computer?
I hope someone can help... 2007 cadillac SRX with 75,000 miles has the check engine light on ( and tire light on). The check engine code is bringing up a bad 02 sensor. Replaced all of them and it still tells me bad 02 sensor. So we replaced the cat. converter. STILL throwing up the 02 sensor code! Any insight? Is in a bad computer... which is why I bring up the tire light being on as well. We tried a million times to clear that and it won't clear either, tires are fine. Thank you for your time.
