behind the cat converter.

ok so the person at the auto parts store gave us a sensor and the sensor that we have is located under the hood. we go through the wheel well to find it
no, sensor 2 is under the truck behind or downstream of the cat converter
Roy
im just trying to make sure im not confused and we are replacing the right sensor i mean he went off the code to find the part. i guess i am just paranoid it isnt the right one cause i always assumed it was under the passenger side front door
ok i understand now i am pretty sure he gave us sensor 1 instead
first of all, bank 1 is the drivers side. and yes, it would be under the drivers door, not through the wheel well
dont be surprised if the sensor does not repair the truck. a code never identifies a bad part, just a failed system.
you got the opinion of a parts salesman, not a technician.
Roy
ok, bank 1 is the front group of 3 cylinders.
Roy
ok so the sensor 2 for that one would be under the door or by the wheel well? sorry im just really confused and cant find anything online except you and it is much appreciated
yes, that would be correct and your welcome.
