My engine throws a o2 sensor code...I replaced the o2 sensor with a new one and the check engine light still comes on after I start the car, I also check to see if it was still throwing the same code and it was...what do I do????

 

reset the ECU?

 

pull the 7.5 amp back up fuse. you will have to reset the radio after. so if you have a anti theft radio make sure to get the code. if you pull the - battery cable make sure to let the car idle for 15 mins with no a/c on to learn idle.

I have already done all the above and still the check engine light comes on???

 

short in the wire? if u disconnect the battery for awhile and reconnect it and let it idle it should be fine that is the only thing i can think of

 

well if all the wiring is good and the sensor is good open the ecu up and see if any of the drivers are burnt
