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.
