I did some exhaust and cat converter work on my truck and I opted to leave a few things out rather than cough up the estimated 900 for a new converter and labor. The O2 sensors make the CEL stay on and I would like to have the light off and working in case anything else goes wrong.Is there a good workaround for those sensors?

The first sensor is essential for the fuel injection system. Without it, the truck will run very rich. The rear sensor only checks for the function of the catalytic converter. this one can be bypassed sometimes by putting a spark plug non fouler on it. give it a search on this forum.

 

you got to do something with the precat o2 sensoe like stick it in a pipe my 2nd o2 sensor is ziptied under my truck and I have no CEL if you want a pic of my 2nd o2 sensor I will upload one
