On the exhaust pipe between the exhaust manifold and the catilitic converter. Looks kind of like a spark plug screwed into the pipe.
If you mean o2 sensors, there is one. It is located on the exhaust manifold on the back side of the engine. Gm started the two o2 sensors around 94-95 when obdII was adopted.
One, just before the catalytic converter.
All O2 sensors are threaded into the exhaust system at various points. Upstream O2 sensors are located before the catalytic converter(s) and downstream O2 sensors are located after the catalytic converter(s).
There are four o2 sensors on a montero sport.
you got 2 sensors,both in the exhaust ,1 before the converter and another after the converter,Danny
The 2.5 has 2 O2 sensors (both on top of the engine) and the 3.5 has 4 O2 sensors (two on top, and two under the car).
The o2 sensors screw in. There is a special socket for removing the 02 sensors with a slot in the side to clear the wiring.
All the O2 sensors are threaded into the exhaust system at various points.
The O2 sensors are located between the exhaust manifolds and the cat converter. They screw in to the head pipes. Those are also called upstream O2 sensors and in some vehicles they are also called air/fuel sensors. There are also downstream O2 sensors that are located after the catalytic converter.
All O2 sensors are threaded into the exhaust system at various points.
how many o2 sensors on a ford e350 van 2003
if you disconnect the o2 sensor cable in the air intake then start the engine you would see the check engine sign turned on in the gauge panel. It is on then the sensor is working if off the the sensor may have problems
