I just installed a brand new PFC v. 5.08 into my 93 cali car. i cut the appropriate wires and when i turned the ignition key to the "on" position the exhaust temp warning light is on. I look in the commander and I don't see any sensors that indicate abnormalities. To my understanding this light is suppose to be OFF when things are all ok. I don't quite want to start. also have the fan mod done... the one where you car stays on after u turn it fof.. could that be cause it? anyone else sovle this problem?

 

That warning light is so pointless. I would probably just unplug it. I don't think that was the answer you are looking for but sometimes simple is better.

 

FD3boost- on a PFC equipped car... the overtemp light serves as the CEL.





disconnect the battery and press the brake pedal for about 10 seconds and reconnect it. It's possible that it picked up an error and held it during the install.

 

Whoops. we don't need to stinkin check engine lights essay! Sppss spppss

 

thats probably the only warning light ive never seen come on

 

trying to get this straight... in the manual does "on" mean with the engine started? or does "on" mean with the key in the on position...?

according to this thread

"on" means with the engine running.

 

it is normal for the overheat exhaust temp light to be on when the key is in "on" position without the car actually running



it should not be on when the car is running and your key is in the "on" position.
