Does this light ever come on, is there some sort of sensor, is it even active?

I see it when i turn my car on, and i wanted to know if it works at all, and if anyones has ever came on

Thanks alot,
Derek

 

Supposedly it works, I havent ever seen it illuminate though. There is an under floor sensor that triggers it off.

I have seen it light of once. Don't know why the hell it would be a danger?


DANGER TO MANIFOLD!!!!!!!!

 

It came on in my base when the cat was clogged and glowing brighter than jrat when he see's a bottle of beer.

 

Don't mind the *****, er postwhore that is.

 

yeah, when I ran that 1000 shot of NOS it lit off, but that's probably because I forgot to double clutch .
Is the exhaust overheat sensor that thing under the passenger seat bolted to the floor? My friend and I have seen it, but we couldn't ever be sure what it was for.

 

Yep, that's it.

 

Thanks alot

 

LOL. If it is under the passenger seat, then you must really have to get that exhaust hotter than the fires of hell to set that bitch off.

 

Not entirely, considering the cats should be running right underneath there.

 

Heh, right. I almost forgot.

 

If the exhaust is hot enough to set that sensor off, you could be in danger of detonating the air/fuel mixture from a hot spot in the block before the spark plugs ignite it. Thats my theory and I'm sticking to it

 

yank dem cats out of your car anyway, she'll show her appreciation for it.

 

I never even new the sensor worked or have heard It work until now. It was the 2nd last connection I made when I replaced my Front Engine Harness with a brand new one.

 

Anything that causes excessive exhaust heat can set it off, like clogged cats, improper mixtures,etc. If it turns on, don't ignore it.

FYI, JDM cars like mine don't have the sensor under the floorpan; it's fitted directly into the cat instead. This means I don't have that sensor anymore...

 

Yeah, I was wondering about that light? I drive til the turbo is glowing like hot coals and it never lights up...Maybe it needs some nos to check if its still functioning......heh
