Morning - been reading all the threads on this for the past few hours.
2006/V6/50K miles. Codes scanned at Autozone, took codes to dealer, they said replace pass/front O2 sensor. Ordered one, changed. Code still there.
-I did not do the neg batt cable off to reset yet, but will do today and see what comes up (or hopefully doesnt come up).
Are all 4 sensors the "same part" or do the front/rear sensors differ?
I feel silly for asking, but what is the best way to check for exhaust leaks?
