upstream o2 sensor replacement

ive located where both upstream and downstream sensors are...where is the plug end of the upstream sensor located at?

 

follow the cable up. It should only have about 6 inches of cable, unless your is a manual tranny, then its underneath your shifter housing.

 

thanks for the info brother....and thanks a million times over for your service to our country!!

 

i just replaced mine, and it works best like this....go to the downstream 02 sensor and unplug it (it gives you more slack when you pull the main harness wires looking for the upstrean sensor connector) when you pull the main harness wires you will see the upstream 02 sensor wire tucked away on top of the tranny begin to come out...then its just a matter of unplugging and replugging up the new..

 

do you get a check engine light when the upstream sensor has gone

 

yes it does.

 

On my 03 manual, the upstream O2 sensor connection is on top of the gearbox. I had to get to it by removing the console and going through the hole where the shifters are located. It was mounted on a bracket that was bolted to the top in front of the shifter. Had to take that bolt out to pull the connection back to the hole so I could get my hands on the connection.

 

This! I did mine this way on Friday .
