Oxygen Sensor: Testing and Inspection
Sensor Heating Element Test
Use an ohmmeter to test the heating element of the oxygen sensors:
-
Disconnect the electrical connector from each oxygen sensor.
-
The white wires in the sensor connector are the power and ground circuits for the heater.
-
Connect the ohmmeter test leads to terminals of the white wires in the heated oxygen sensor connector.
-
Replace the heated oxygen sensor if the resistance is not between 4 and 7 ohms.
