Have a trouble reading bad O2 sensor and O2 sensor heater. Went to look under truck and the sensor behind the catylitic converter have cut wires! I can't tell where they went to. The Check engine light has been on since I bought it and just recently started driving. Where should these missing wires lead to? Thanks

Hello,

If you cannot find other cut wires somewhere near then it is possible that it has been disconnected at the connection. Which could be a foot or more away from the cut wires. Take a look at the other O2 sensor connection then look under the vehicle and see if you can find that connection. Also might be easier since you should replace that sensor to get the new one and install it then stretch the wire out to find the area were the connection should be. Post finding.

Ok, Thanks for your speedy reply. I did find a plug not too far away from the wire-cut sensor but it had 4 wires and my sensor has only 3. There appears to be no extra wires whatsoever at the other 2 sensors. The spit there is neat and clean.

That's ok it only indicates that the sensor is not heated. That is what the 4th wire would be for.

Thanks so much. So that must be the plug I need to go to. As long as a new sensor has a wire about a foot long. Thanks so much for your speedy help. I tried to give you feedback but only have.1 points and it wouldn't let me do it. Thanks a lot!
