one
I believe there are ( 4 ) Bank 1 is the passenger side of the engine , sensor 1 is before the catalytic converter ( upstream ) and sensor 2 is after the catalytic converter ( downstream ) Bank 2 is the driver side of the engine , sensor 1 is before the catalytic converter ( upstream ) and sensor 2 is after the catalytic converter ( downstream ) The 2 sensors before the catalytic converter are used for air / fuel ratio for the engine The 2 sensors after the catalytic converter are called catalyst monitors
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).
They are threaded into the exhaust system, one before the catalytic converter and one after the catalytic converter.
before and after the catalytic converter.
All O2 sensors (AKA Air/Fuel sensors) are threaded into the exhaust system. Some before the catalytic converter (upstream) and some after the catalytic converter (downstream).
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?
2, one before the catalytic converter and another after the catalytic converter.
All O2 sensors are mounted in the exhaust system. There will ususally be one before the catalytic converter and one or two after the catalytic converter. All O2 sensors are mounted in the exhaust system. They look like spark plugs with wires on the back in the exhaust. There will ususally be one before the catalytic converter and one or two after the catalytic converter.
There is one and it is before the catalytic converter.
Two, one before and one after the catalytic converter.Two, one before and one after the catalytic converter.
There are usually two of these sensors, both are located on your exhaust system, one before the catalytic converter and one after the catalytic converter.
There is two oxygen sensors. One is located before the catalytic converter is located under the heat sheld. The oxygen sensor after the catalytic converter is found under the catalytic converter (under the car) before the catalytic transfer pipe.
