Hello everybody,
Im new to the forums. I drive a 98 e36 323is and have been having overheating problems lately. My check engine light is lit so i took it to autozone to have them do there free diagnostic check. They came up with the code P0141. Also, on the paper it describes
"Definition
Heated oxygen sensor- Bank 1 Sensor 2 (h02S12) B sensor heater circuit
Explanation
BBOpen or short circuit condition
Probable cause
BB1- Poor electrical connection
BB2- Faulty HO2S12 (bank 1 sensor 2) "
I've had mixed reviews on why my car is overheating. Many people say that my cat is bad and causing exhaust gas buildup in the block and causing the overheating. Others tell me that my O2 sensor is shot and i need to replace it. I also believe it is the O2 sensor, but i would like to be a good amount certian before I go and spend the $120 on a new one. This problem arrised after i had the CAT taken out and welded back in, if that would cause any difference. Any help greatly appriceated.
Thanks and Godbless,
Logan
