I assume you asked, because you haven't looked for them, and never removed one before.
They are always in the exhaust pipe before the converter or most are in the converter.
A 22mm or 7/8" wrench may be what you need
Usually, you use a special O2 Sensor Socket,there are different ones.

Don't replace without testing first
OBD2 Codes--for O2 Sensors --doesn't mean it is bad,could be a vacuum leak.

I have a Pontiac Grand Prix GT, 3.8 Liter Motor. Two codes PO108 Map/Baro CKT High Input, and PO121 Throttle/Pedal Position sens A ckt Rng/Perform, according to the scanner. Did I need a Map Sensor and...


Change the throttle sensor first, and see if the map sensor is a victum. throttle sensor is similar to an old volume reostat, on some cars and everything else tries to do react, and everything errors out.... My bet is throttle position sensor... But you never know, it CAN be both, just usually not both.

Check the mass air flow sensor on the throttle body. It may need cleaning or replaced if the filament is broken.

2001 grand prix gt 3800 engine started boging down changed fuel pump and filter still doing it sitting still at high rpms it boges an its like its loosing throttle


try taking the oxygen sensor out of the manifold by the firewall and take it for a ride,it sounds like u have a plugged catalytic converter,by removing the sensor your givin the pressure somewhere to escape,if u do have to replace the cat converter i would suggest putting a factory converter on it because if u dont, the check engine light will come on due to the fact that aftermarket converters only have three of the four precious metals required to work properly thats why they are cheaper

I got a 1997 pontiac grand prix gtp coupe. the low coolant light constantly flashes. the coolant fluids are full. i just bought it and i am a little frustrated.


Sometimes the float in the low coolant sensor gets stuck.Find where the electrical connector is on the overflow tank and lightly tap on this area.This might dislodge it,if its stuck.Good Luck!!!
