Just one.
2 1 before the catalytic converter (more expensive one) and 1 after.
they are on exhaust pipe one is upstream of catalytic converter and one after 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).
All models have one, though it differs sightly if you have a DOHC. Most aftermarket O2 sensors for the 92 Prelude fit all models.
Yes, there are 2. Its an obd2 car all obd2 ( onboard dignostics 2 ) cars have 2 - 4 wire o2 sensors.
all o2 sensors mount in the exhaust, normally with one mounted in the manifold, or somewhere in the exhaust pipe in front of the catalitic converter. the other one should be mounted either in the catalitic converter itself, or in exhaust pipe just behind it.
There are four o2 sensors on a montero sport.
Single exhaust? Look before and after the converter. O2 sensors measure oxygen content before and after flow through the converter.answerThe oxygen sensor is a spark plug shaped device that is screwed into the exhaust manifold. Answer:There is one sensor located before the cat convertor. It will be a 3 wire sensor.
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.
