Want this question answered?
they are located in the exhaust system Where ? how many 02 sensors on a 2003 Pontiac Montana
usually 02 sensors are located on the catylac converter OR the manifold
Hi. There are 2 sensors. 1. Is just in front of the cat. 2. Is just behind the cat.
If it has the 2.2L engine it has two. If it has the 4.3L engine it has three. All O2 sensors are threaded into the exhaust system at various points.
There are several 02 sensors on that vehicle and they are all threaded into the exhaust system at various points.
O2 sensors measure the amount of O2 in the exhaust so they are usually right after the exhaust manifold(s). I do not know Nissans but usually they will screw out. HTH

Most oxygen sensors are heated oxygen sensors.
The 02 sensors are in the exhaust pipes but don't know about the updraft sensors.
The pre-cat O2 sensors are (from standing in front of the engine) to the left of the engine, on the top of the exhaust manifolds. The post-cat O2 sensors are seen from under the vehicle at the end of the exhaust manifolds.
There are 2 upstream 02 sensors just behind the exhaust manifolds, threaded into the exhaust pipes, one on each side. There are 2 downstream 02 sensors just behind the catalytic converters, one on each side as well.
The vehicles computer relies on the information from the 02 sensors and other sensors to adjust the engine for peak performance.
