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 two oxygen sensors. One is located in the exhaust manifold inside the engine compartment. If you have a 4 cyl model it will be where the 4 pipes merge in to 1. The second sensor is located after the catalytic converter.
I can only find two sensors, engine compartment, pre and post catitytic converter. Ideas, suggestions .......... help, please? Where are the missing two?
Usually on or near the catalytic converter.
The engine will not run properly with out a functioning catalytic converter and working O2 sensors.
there are 4 sensors. 2 pre cat sensors and 2 post cat sensors. the pre cat sensors (both) are located in the overhead engine compartment towards the passenger side. the post cat converter's are located underneath and to the mid section of the engine and a pain to get to. hope this helps.
2 sensors. One is on the back of the engine near the wall of the engine compartment. the second one is on the exhaust pipe under the middle of the car near the catalytic converter. if you change both and you still have a check engine code. it may be the catalytic converter that is bad
In the exhaust between the engine and the catalytic converter.
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.
there are two sensors, one located before the catalayic conveter which is accessiable from under the hood towards the back of the engine compartment and the second is located under the vehicle after the catalayic converter.
There are 2 sensors. One in front of the catalytic converter and one behind it.
There are 4 sensors,,2 before the converter and 2 after on the exhaust system
before and after the catalytic converter.
There are two sensors in that exhaust system. Only one is called an O2 sensor and it is located in the exhaust system after the catalytic converter, also known as downstream.. The other sensor is called an Air/Fuel Sensor and is located before the catalytic converter, also known as upstream.
Oxygen sensors are screwed into the exhaust on both sides of the catalytic converter.
look under you Chevy and locate the catalytic converter. Your 02 sensors are located before and after the catalytic converter on your muffler. See 1 or 2?
All oxygen sensors are located in the exhaust either before or after the catalytic converter.
It has one, it is located in the exhaust in front of the catalytic converter.
before and after the cat converter
They are on both sides of the catalytic converter.
o2 sensors are on the exhaust pipe one you can see from engine compartment and the other should be behind catalytic converter on same pipe.see it from underneath car .
There are 2 oxygen sensors on an 04 frontier pickup 2.4litre. One is located after the catalytic converter (on the exhaust Pipe) and the other is between the exhaust manifold and the catalytic converter.
There are multiple O2 sensors on a 2002 Chevy truck. They are all located on the exhaust system. There will be pre catalytic converter and post catalytic converter sensors.
O2 sensors or Air/Fuel sensors are found threaded into the exhaust system. Sensor 1 is located before (upstream) the catalytic converter while sensor 2 is located after (downstream) the catalytic converter.
There is one located in the exhaust, just in front of the catalytic converter.
