Question??? a few months ago I paid $200 to have 1 of my oxygen sensors replaced. now my check engine light is on AGAIN and I think the other one went bad. Does anyone in the 757 know how to replace that if I purchase the part and make sure that is what's wrong??? Let me know!

 

Remove it form the exhaust, wire up the new one, insert the new one.

I guess it might depend as well as to location of the sensor. I'd have the codes checked before going and messing around with it, just to be sure.

 

Check codes, like merf said. If you get a stock O2 sensor, it will have the same connector as the one that is currently on your exhuast, so it will be really easy to replace. But don't just go blindly replacing things, find out what's wrong first. If you've killed two O2 sensors in a short amount of time, there is usually a reason.

 

Thanks ya'll. I checked my gas tank and I think my tard @aa boyfriend forgot to tighten it so I am hoping that is why the check engine light came on. I will find out after work.

Hahaha! What kind of car is it, btw?

 

2003 accord. I figured it was the back oxygen sensor after the convertor because I already had the front 1 changed.....NOT MY FAULT LOL
