Oxygen Sensor Question
 

If you pull a code for the left side O2 sensor does that mean both O2 sensors need replacing. Thats what I'm getting from the how to page under "pulling the codes" section. I just replaced the left side and didn't catch it before ordering the one. Can someone confirm or deny this. Thanks for sharing the knowledge in advance.

Since I replaced my stock exhausr system, :rolleyes: my un insulated system is much harder on O2 sensors. If it says left side, only replace that side. If later it says the right side is bad, go for it. Tom

I think that if you are going to have someone do the work it may be worthwhile to have them both done at the same time if neither have been replaced before. That way you can save some time and maybe labor. I think a new one will last at least a 100k miles.

The code will show left or right. I may be wrong, but I think the 95 has a third sensor on the main cat.

Nope. Only '96 and '97 have the third O2 sensor.
