How to diagnose O2 sensor heater circuit failure?
The modified test harness with the light will give you easy access to the circuit. Remember, the engine needs to be running at this point. If the voltage is close to zero on the positive heater wire, then locate the open circuit in the power wire back to the fuse. Again, it may have a relay in the circuit as well.
What should I do if my O2 sensor shorted out?
In that case, first check for a blown fuse. If the O 2 sensor’s heater had shorted out, the fuse may have blown as well. Once you determine that the fuse is okay, check for voltage at the O 2 sensor harness connection. The modified test harness with the light will give you easy access to the circuit.
When does an oxygen sensor fail in a car?
As vehicles grow older, there comes a point when the oxygen or air/fuel ratio sensor’s heater circuit will probably fail. When that happens, the easiest fix is to install a new sensor. But when the vehicle comes back two days later with the same heater code, what then? A local shop called me in on just such a case.
What kind of light bulb to use for O2 sensor?
When testing the O 2 sensor’s heater circuit, I found using a #7440 incandescent light bulb and socket very helpful. You connect the light to the vehicle’s O 2 sensor heater harness in place of the sensor. The light bulb draws about 1.75A at 12V. This is usually within the operating range of the sensor’s heater.
