How to Test an Oxygen Sensor? - Curiosity Insight

Broadband oxygen sensors are used to increase the accuracy of the fuel and air ratio in the engine. O2 broadband sensors are equipped with a five-wire system instead of the traditional one- or three-wire sensor. The oxygen sensor measures the amount of that substance that enters the engine at a particular time. The sensor transmits that information to the engine computer, which allows ...

How to Test an o2 Sensor with a Multimeter - Hand Tools ...

Test the oxygen sensor to observe how it responds to the consumption of fuel scenarios. Disconnect the hose from PVC (positive crankcase ventilation) valve at the valve cover. This step will allow entry of more air into the engine such that the multimeter reads about 200Mv. In case the multimeter fails to detect appropriately, the oxygen sensor is faulty. Connect the PVC hose back. Test the ...
