We have a 1997 geo metro the check engine light was on when we took it to deq we got the code p0141 we replaced both o2 sensors but the light is still on what else could it be

oop. my bad, did you push reset in the scan tool First ? then drive to see if P0141 returns. that is first, its , SOP , standard Oper. proceedures.... goes without saying, as is bad wires make sensors fail.... oop. my bad, did you push reset in the scan tool First ? then drive to see if P0141 returns. that is first, its , SOP , standard Oper. proceedures.... goes without saying, as is bad wires make sensors fail....

point 2, the Canadian metror's are different and the changes major came in 1998 , not like in USA where it was 1996. for OBD2 compliance.... so is car USA or Canada. point 2, the Canadian metror's are different and the changes major came in 1998 , not like in USA where it was 1996. for OBD2 compliance.... so is car USA or Canada.

just got 3 or 4 cylinders they had 3 engines, in that car in use, world wide 7. ok it fails smog, why not tell how many wires were on that sensor, 1, 3, or 4. and varies by engine, country , and even if calif car, yes, calif has there own setups. same as today, same deal.. if in usa, open hood , look up. see that EPA tag there in white it tells you what engine is there. just got 3 or 4 cylinders they had 3 engines, in that car in use, world wide 7. ok it fails smog, why not tell how many wires were on that sensor, 1, 3, or 4. and varies by engine, country , and even if calif car, yes, calif has there own setups. same as today, same deal.. if in usa, open hood , look up. see that EPA tag there in white it tells you what engine is there.

he ECU can be reset 3 ways, battery plus cable off,, or pull ECU memory fuse (dome?) or scan tool reset. 3 ways. then see if it comes back DID IT: the 141 DTC, they will auto reset but can take like forever. it seems,.
