where is the oxygen sensor located on a 97 pontiac grand am gt?

Answer 1

Follow the exhaust manifold from your engine down toward the muffler. Somewhere in between the engine and the muffler you'll find it or them. usually close to the engine. Where the pipes go from 4 to one... Or from 3 to one on one side and 3 to one on the other. Depending on which engine you have

Answer 2

There are four of them and Dodge Man is correct. There are two (one each) next to the exhaust manifold, and one (each) downstream of the catalyic convertors. Most V-6 engines have 4 of these because of having two banks of cylinders. OBD2 regulations have a lot to answer for on this one.

Answer 3

There can be one to three of those on the Grand am depending on the engine size. Always located on the Exhaust system.

Answer 4

that depends if you have a upstream or downstream sensor bad. the upstreamis near the manifold or right in front of the cat. the downstream is behind the cat, this one rarely fails normally the cat fails first.

Answer 5

on four cyl. engines one up stream in the exhaust manifold
or in the down pipe and one after the converter
on v6 engines one on both manifolds and one after the
converter

Answer 6
