What to do if your oxygen sensor stops working?
If you’re having a hard time unplugging the sensor wire, push the tab down with a flathead screwdriver as you pull the connection back with your free hand. Avoid attempting to cut and then solder the wires to the new oxygen sensor. With modern sensors, soldering causes the wires to stop working correctly.
What’s the best way to change an O2 sensor?
Unplug the wire at the connector and remove O2 sensor. They do sell a special tool, but you can do it with a crescent wrench. Use some liquid wrench first. Apply anti-seize to the threads of the new O2 sensor for ease of installation and reconnect the wire.
How is the O2 sensor connected to the ECM?

Learn about the O2 sensor electrical connection and how it relates to the ECM and signal output. Presented here to help you understand the O2 sensor from an electronics and wiring diagram point of view.
When did they start putting oxygen sensors in cars?
Then, slide a jack underneath one of the vehicle’s jack points. After lifting it up, place a jack stand there to keep the car elevated. Starting around 1994 and 1995, manufacturers started making vehicles with 2 oxygen sensors. The second sensor is only accessible by crawling underneath the vehicle.
What should I do if my O2 sensor is not working?
Then clear the codes. Some computer systems will shut the O 2 heater circuit off until the codes are cleared. Now, with the ignition switch off, plug the test harness with the light into the vehicle’s O 2 sensor harness connection. The light should remain off until the engine is started.

Where is the O2 sensor on a Jeep Grand Cherokee?
In the case I was called in on, the vehicle was a 2000 Jeep Grand Cherokee with the 4.0L engine. The vehicle’s O 2 sensor harness was pinched underneath the valve cover at the back of the cylinder head. Fortunately, the sensor’s negative heater wire was the only wire in the harness that was involved.
