Alright,

So when i was pulling the carpet yesterday, i noticed a sensor which i don't ever recall hearing about, and i tried browsing through the manuals and didn't find anything, I didn't have time to trace back to where the wire was going but i was hoping you guys would know.

The sensor is located right behind the passenger seat rail and has like a burgendish top to it. Looking under the car it seems to be right ontop of exhaust heat shield, Can't actually see where the end is. I took some picture and i'll post them up later on tonight when i get back home if you'd like to.

 

That's the exhaust overheat sensor.

 

?? Now I'm puzzled ... so what was the one hooked to the stock exhaust manifold? there was a tube hanging off the exhaust manifold and and with 2 crews on there held another electrical sensor

 

Actually I should rephrase that .. it wasn't on the manifold it was on one of the tubes about 1/2 way through the car ... thats what i thought the over heat one was.

 

dunno. But the sensor on the floor is the overheat sensor. For sure.

 

Need pictures. There is no tube that comes off of the exhaust manifold. There is a Air tube that comes off the back of the intake manifold and goes to the catalytic converter. It has a check valve at the top near the intake but no electrical connections. It is just for fresh air from the air pump to help heat the cat up for emissions.

 

alright then ... if anyone knows what the other sensor is for let me know ... I have a 12a GSL ... this one comes from under the driver side bin i think if i recall correctly.

 

no thats not it ... like i said its an electrical sensor ... not air tube or anything it was past all the catalytic converter on the mid pipe. jsut a little past the cat

 

It's a Canadian Ale sniffer sensor.

 

Oh ok that's the catalyst thermo sensor.

 

You can find out more about it, for both the cat thermo sensor and the overheat exhaust sensor in chapter 4A of the online FSM.

 

Hey,

Alright, I'll look up in those sections tonight. Thanks for the info.

 

That'll be 5 bux sir, we accept Paypal

 

Oh, I thought it was the Flux Capacitor regulator.
