How to get the O2 sensor repaired?

December 29th, 2010 · No Comments

i have a 99 cadillac escalade and the o2 sensor is failing and i was wondering how to go about getting that fixed and will that stop my car from passing a texas state inspection?
- New one is right. There may be two or three of them though. You’ll have to get the right one or just go one at a time and hope you get lucky early.
- You don’t repair them, you replace them. You just unplug it, unscrew it and put the new one in. A box wrench will go over the connector and onto the sensor when you unplug it.
- Yes, it will stop your car from passing emissions testing portion of your state inspection. To fix the O2 sensor, just unscrew it from the exhaust, and replace it with a new one.
- It shouldnt fail in Texas due to the lack of emmisions tests. Although if you want it fixed your going to have to replace it. In my opinion Id go out and find the place with the cheapest labor rates in town and get it replaced. Sometimes they can be a pain in the rear to replace yourself plus if it has the 5.3L V-8 in it your looking at about 3 different O2 sensors. A shop will be able to determine which one is bad. More than likely its going to be the most expensive one to relpace just because of Murphy’s law.
