Guest fast cutie Posted April 29, 2003 Report Share Posted April 29, 2003 When it comes to replacing an O2 sensor, how hard is it to do yourself? Quote Link to comment Share on other sites More sharing options...
Guest Ranger_Man Posted April 29, 2003 Report Share Posted April 29, 2003 depends on where its located. e.g. can you reach it and have enough room to work in that area. usually o2 sensors seem like they are an afterthought and stuck in some stupid place that only midget hands can access.

Holy SHIT... The sensors themselves can be expensive (i.e. couple hundred if you're really unlucky), but Lord that sounds bad. Quote Link to comment Share on other sites More sharing options...

Guest stevil Posted April 30, 2003 Report Share Posted April 30, 2003 The O2 sensor behind the catalytic converter isn't important. All it does is make sure your cat is working correctly for emmissions, shouldn't hurt performance. If you're worried about a "Service Engine Soon" light on your dash bugging you or something like that, you can get a new O2 sensor and replace it. Otherwise, it's no big deal to just leave it. And it shouldn't be hard to replace, if you have some basic tools (jack, jackstands, wrenches, etc.). On my car, changing an O2 sensor after the cat would be cake, if I had one. tongue.gif The 2 pre-cat sensors on the other hand... one is a tough bitch, the other is easy. Some cars have the cat built into the exhaust manifold, which means it's closer to the engine and in a tight spot, and not under the car and easily reached. Look under the car to see if you can see the catalytic converter, should be bolted or welded into the exhaust piping. If you see it, should be fairly easy to replace.
