Coolant temp sensor/ fan control chip
ok My fan control chip is fried on the ECU board i was just wondering will this prevent the proper operation of the ECU? or does it only turn the fan on/ off? i am asking cause i have replaced the CTS and the O2 sensors but when i check to see if the car goes into Closed loop it dont the light just blinks fast and never slows down. also related to this is that the EGR chip that is right next to the fan chip is a bit brown is it probably damaged to no inoperability? i question this cause i have replaced the EGR valve and the related things and it still will not work. also any ideas as to what would cause that chip to litteraly get so hot that it explodes? how can i add a pic?

I had my computer also fry, same thing.
I replaced it and never a probelm since.
But right now I do have cooling fan issues I solve by using AC all the time.
Replace the computer by using ANY
60*V6 MPFI ECM
ONLY FOR 1985!! MODEL YEAR
AND READY
1985 Corvette, too!
ANY other thought of vehicles, ya better check the Hollander book.
Cause that's where I got my information.
And I threw in a 1985 Corvette ECM and my ORIGINAL VEHICLE PROM
And all was fine.
But I do need to change my CTS very soon.
This will (fried ECM) affect the fan operation.
My fan stayed on all the time.
Replacing ECM fixed the problem as my ECM was that fried as yours.
And so ya know no there were NO performance gains using the Vette ECM!
