Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
what model Chevy is this ?
where under the track area do you see this hanging plug from and is it not plugged into anything or are the wires cut or ripped out ?
the odds are that is the rear 02 sensor which is located in the exhaust like this picture
it connects up in the rear of the engine compartment near the power steering rack
if the wires are hanging down it became unplugged are the wiring broke and will need a new 02 sensor
most shops can change out a new 02 sensor for 1 hours labor
if it is just unplugged with no damage to the connector you can open the hood and with a good light look down the bottom of the fire wal down where the rack are is and it should plug into a connector in that area
more so the drivers side and it can be reached under the car or under the hood through the top reaching down
i wish they listed a picture of it to show you the location
should be a square connector
