Well I'm in quite the bind, I have an 02 corvette that is constantly throwing the engine code p1153 for my first O2 sensor on the passenger side. Which means the O2 sensor is not switching from rich to lean enough times.. I have gone through three sensors and even a new CPU! I've taken it to my local GM dealership where they couldn't figure it out either! Only thing I can think of is I changed my head gaskets without taking them to a machine shop to get decked and maybe I have coolant leaking into the exhaust giving a faulty reading.. Because I do smell a little coolant. Would that effect the 02 sensor in that way? Any help would be greatly appreciated for this is starting to piss me off! Thanks!
-
Yes. It's possible that the coolant leak is contaminating the O2. Coolant, engine oil and/exhaust leaks are listed in the factory service manual as possible causes for setting the P1153 code.

Other than the O2 sensors I have seen any other problems triggering the P1153 code. Do you have any other symptoms or codes? any exhaust leaks?
-

-
Any other codes or symptoms? other than the oxygen sensor I haven't seen any other component triggering the P1133 code. I have also check a national database of repair for your model year and the sensor is the only thing that fails. Are there any leaks exhaust leaks?
