WHERE DO I FIND THE OXYGEN SENSOR FOR A 2005 CHEVY COBALT

SOURCE: my 2005 chevy cobalt factory radio is locked

There are only 2 things you can try to fix this yourself: turn off the engine and open the driver side door (to turn the radio off). Wait 5 minutes, start your car.
If that does not solve it, turn off your engine, disconnect the car battery, wait about 5 minutes. Reconnect the battery (negative pole first - black connector) and try your radio again.

If neither one of these two fix your problem, I am afraid only a GM service center or dealership can fix the problem. The Cobalt is notorious for all kinds of electrical issues.

Thanks for using the fixya forums!

you need to rent an 02 sensor socket and use a ratchet and the socket to remove it, there are two on the exhaust pipe one before the cat, you can see it on the exhaust pipe and one after. normally the 1at one goes out. cost $75.00 please rate if helpful.

disconecting the battery should reset the pcm. but you will need to find out what caused the problems.

Need a 7/8 open end wrench or a o2 sensor socket. Located in exhaust pipe. The one closest to the engine is Bank 1 Sensor 1. The ones located downstream and known as "Sensor 2"

There is a special socket for O2 sensors which allow the wires to stick out and not get twisted up. It's not expensive and available at most auto parts stores. Disconnect the sensor from the wiring harness, with the plug and then use the socket to remove and replace the new sensor. Re-connect electrical plug.
