If the inlet and outlet exhaust streams are monitored, the catalyst efficiency can be measured.
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).
Assuming you have the V-6 engine, it has two downstream (after the cats) O2 sensors and two upstream (before the cats) Air/Fuel Ratio Sensors. So the answer to your question is two O2 sensors.
There are two.
The 1992 Ford Taurus has two oxygen (O2) sensors. Both O2 sensors are located upstream of the catalytic converter with one on each exhaust bank.
two o2 sensors on a 93 mustang 5.0
There are two o2 sensors on this car.
Toyota RAV4's have two (2) O2 sensors.
The are all types of O2 sensors. The front two are the O2 sensors used for fuel control for each bank, and the rear two are O2 sensors that are used to moniter catalytic converter functions on their respective banks.
Yes.
