Respuesta :
Connect the sensor output to your oscilloscope using the proper connection device, keeping the sensor connected to the ECU at all times. Engine speed should be around 2000 rpm. An oxygen sensor that is working properly will have a rapidly fluctuating output voltage between 0.1 and 1.0 volts.
Which of the three oxygen sensors are these?
For the regulation of the air-fuel ratio of engines, three different types of oxygen sensors, namely concentration cell (zirconia sensors), oxide semiconductor (TiO2 sensors), and electrochemical pumping oxygen sensors (limiting current sensors), are now available.
How do the four oxygen sensors work?
There are four oxygen sensors on V6 and V8 transverse engines: a downstream sensor, a downstream sensor downstream, and a right bank upstream downstream.
