screwed into the exhaust pipe, under the vehicle, close to the exhaust manifold
In the manifold or the exhaust pipes
ype your answer here...
That year model did not use are have a crank sensor.
My 1990 Lumina 3.1 had the same problem and it was caused by the crank sensor.
The oxygen sensor is usually mounted in the exhaust manifold pretty close to where the exhaust pipe bolts on.
on my 1992 lumina z34 its about 5 inches from top on passenger side of car directly below radiator fill spout
where is the o2 sensor located on a 1992 Chevy s-10 4.3 ?
behind the harmonic balancer
on the backside of the block toward the firewall if I remember correctly.
Either a O2 socket & ratchet or a 22mm wrench. Best find out which sensor first as you could spend lots of money guessing
In the exhaust manifold on the back of the engine.
That vehicle has several O2 sensors and they are all threaded into the exhaust system at various points.
