RE: Failed o2 sensor
Has anyone else here had any problems with they're o2 sensors dying on them?
I've had my car for a year and a half and have a AF gauge for about 8mo. now and my CEL light came on and I took it to the dealer and they said its my o2.
Anyone else have this?

He didn't say what the code was. They just said that they were unable to perform tests on it b/c the gauge was interfering w/ the signal.
Now I have two questions. First, does anybody know what brand of o2 sensors Mitsu uses? Are they Bosch?? Nevermind, they are. I looked into it. heh
Secondly, can anyone here see/explain how a device used post operation (b/c it doesn't interfere w/ a signal and all a o2 does is transmit info right?) cause fault w/ a part? I personally think they're being stupid.
I want to have some proof JUST IN CASE they try to do anything. Now, if it turns out through my research that a gauge CAN damage a sensor then I'll suck it up and pay. I'm not trying to get out of paying for something here. I just think they are.

Joe, the dealer said the sensor may already be damaged. Besides, you and I both know its not the sensor. I've had mine for 8 mo. you've had yours for some time as well. Have you ever had a problem like this? Probably not.
It just sounds like the dealer is looking for a way out. But, Like I said...lets see what transpires next time I go down. They said they have orderd a new one to see if that clears the code.

the guage only reads the signal being put out buy the O2 sensor, it doesnt send anything anywhere so there for cant interfear with the guage. tell the techs to go back to automotive school and electronics again. but seriously its just a pretty light that reads the singnal from the sensor nothing more.

Try to find out what the code was. It will help us a lot if we know what's causing your CEL light to stay on.
Malfunction / Slow response / Lean / Rich / Shorted / ect.....
I'm also running an Autometer A/F gauge for 2 1/2 years ..... no problems. Prior to that it was on my previous car for 6 years and no problems.
Putting a new sensor in won't clear the code. The light might go out but the code will be stored in the ECU. Only way to clear the code is by using a scan tool or disconnecting the battery.

Oh, I and I know about clearing the code w/ the battery disconnect. I did that the first time the light came on a few days ago. It came back the next time I drove.

It should have stayed on the Lean side ( red light ) when you first started it. It will stay there until your Cat is warmed then it will switch back and forth.
When you say Spastic do you mean faster than what it used to be ?

Faster AND it has a tendancy to pulse further into the RICH bar then not. But then it may also just stay on the lean side pulsing back and forth quickly as well. Thats what I meant by spastic.
Any idea why the CEL light would go off though?
