In a 1996 pontiac sunfire there are 2 oxygen sensors .. one on top.. one on bottom of engine. i need to know where exactly they are located and how easily they are accessed


Oxygen sensors are always located in the exhaust system. The top one you refer to is likely on the exhaust manifold, or just after on the exhaust pipe, but before the catalytic converter. If you have a v-6 there may be one on each bank of the block in the exhaust manifolds. Then, there is also an O2 sensor located in exhaust, after the catalytic converter, to monitor efficiency of the converter.
Both should be fairly easy to access. Good luck.

1996 pontiac sunfire code reads too lean bank 1. What do I do?


Hi..my name is Keith...and the oxygen sensor(s) sends a signal to your computer to control the richness or leanness....and bank 1 is the exhaust pipe comming out of the drivers side of the engine..so..you probably need to replace the O2 sensor(s) or you could have dirty fuel injectors..not letting enough fuel into the cyclinders..i hope this will help

MY 97 PONTIAC SUNFIRE IS BURNING A LOT OF GAS


Is the check engine light on? If you have a sensor that is bad, it will cause bad fuel mileage. Especially if it is an oxygen sensor. It might just need a tune-up.
