The stock cat rear o2 sensor was cross threaded, and many people I have talked to have had the same problem. Does anyone know which universal if any o2 sensors work with the car. The dealer wants over $350 bucks for the rear 02 sensor and I think thats a little high for an 02??? Any Comments about sensor replacement would help a lot! The sensor is bad by the way, I checked it at my friends shop it has no output signal only input...

 

Bosch or NGK make them usually.

 

I have one that I took off a wrecked evo I'll sell you for $75 shipped.

 

Call me and I'll do it....Its not stripped out is it? ( Stupid Question ) but just checking....

 

I don't think it's stripped as far as I know (it came out of the exhaust without any problem), but I'm not a fan of talking on the phone (ask anyone here local).

 

ok so how do we do this then since you don't talk on the phone??

Also is it the whole wire loom connected, not just wires cut half way to sensor?

 

Do you still have that O2 sensor?

 

Guys, it's been weeks, I sold the sensor to Chuck. Quit PM'ing me.

 

haha thats funny thanks by the way it worked fine

 

If anyone else has an OEM rear O2 sensor for an EVO X, please PM me, I need one as well (mine stripped to hell on the way out).

 

Yeah a lot of them do that I think the JAP in charge of screwing in the O2 sensor in the Cat should be fired! Also I finally beat the sensor, you have to drill out the first spark plug non fouler and leave the second one as is. I havent had a light now for over two weeks!!!
