[QUOTE="Kate Andreozzi, post: 1018970, member: 67608"] Helping out my sister who had a check engine light on. She has a Hyundai Elantra. Went to Autozone and had the code come up as P0139: H02S12 circuit condition (heated oxygen sensor bank sensor 2). Probable cause was oxygen sensor defective, fuel system running rich or lean, engine misfire, or fuel pressure very high or low. Is there anything I can do before bringing it to a mechanic? I was thinking of cleaning the O2 sensor first and go from there. Any suggestions or advice? The engine is running fine, car drives with no symptoms. Thank you in advance. [/QUOTE]
