Please answer the question. "How do you change an oxygen sensor in a 2002 Pontiac Bonneville
The oxygen sensor on a 1996 Pontiac Grand Am is found near the catalytic converter. It will be place on the piping which leads to the catalytic converter.
The 1991 Pontiac Grand Prix oxygen sensor is located on the outside of the air filter housing. You will find the sensor on the back side of the air filter housing.
its before the cat around the header area
To answer this i will need to know whatsize engine you have.
Screwed into the exhaust pipe
on the exhaust pipe between driver and passenger!
That would be the sensor after the catalytic convertor.
if its the v6 there are two but the 4 cylinder has just one on the back side of the motor that plugs into the exhaust manifold the wires run up behind the alternator
were is my 1999 pontiac grand am map sensor location
Bank 1 is usually the bank that #1 cylinder is on (sometimes the driver side while bank 2 is the passenger side) and sensor 1 is before the cat converter while sensor 2 is after the converter.
02 Sensor? should be before the cat
