O2 Censor needs replaced

Go HERE. Scroll down to pictures 14, 15 & 16. It will look like one of those pictures depending on which engine you have. You may not need the special socket if the flats on the sensor are where you can get to them. Unplug electrical connector, remove sensor, screw new sensor in & reconnect electrical connector. Not usually too big of a deal. You'll need to reset the check-engine-light with a scanner.

Have it done in a garage, not worth the headache of doin it urself, believe me.
The O2 sensor is located on the downpipe and has a single wire on it, (usually black, but could have white leads on it).of ur exhaust system and requires a socket that has a slot on it.
The O2 sensor is usually really and i mean really stuck there as its been heated and cooled thousands of times.

OK my name is danny and if you need to know exactly where it is located on your car it should be on the exhaust either before or after the exhaust manifold if you still need help please get back to me and i will gladly help you.
