Have any of you ever dealt with a bad temp reading on the DIC, and it is not fixed by replacing the sensor?
I have had the issue for a while, tricked it with a 2ohm resistor for a bit, but the temp reading would say from ICE to 43F, and it would be 75F out.
I may try to replace the sensor connector..
But the main thing I am trying to figure out without digging out my FSM is where do those wires terminate inside, I have auto climate so I am thinking they come in the big harness with the radio and all, and terminate at the air control unit?
It is maddening not to be able to have AC when it gets really warm, and while we have a cool few days here I figured I'd get on it before the heat of Summer hits..

Hope all of you ole timers are well! ]]> Pontiac WilliamE https://www.gmforum.com/pontiac-168/ambient-temp-sensor-315661/ https://www.gmforum.com/pontiac-168/pk2-problems-315660/ Sat, 02 May 2026 03:39:30 GMT I’m having to replace the BCM in my 02 Trans Am and I don’t want to bypass the pk2 system (also highly unlikely it’s possible because I don’t know the resistance of the key for this BCM) I was... I’m having to replace the BCM in my 02 Trans Am and I don’t want to bypass the pk2 system (also highly unlikely it’* possible because I don’t know the resistance of the key for this BCM) I was wondering if I could use Tech2Win or another software to reset the resistance value stored in the new BCM to recognise the key. I’m going to buy Tech2Win anyway for proper diagnostics for both of my vehicles but just curious if any seasoned GM techs know a way to do this. Any help is appreciated TIA ]]> Pontiac Coreyhall49 https://www.gmforum.com/pontiac-168/pk2-problems-315660/ https://www.gmforum.com/pontiac-168/put-reverse-terry-315655/ Tue, 28 Apr 2026 01:25:20 GMT …sometimes I need a jump to start it it’ll run but when I put it in reverse it’ll shut right down.

So I'm changing out the tensioner. One of the two steel nipples that mount to the tensioner with a bolt that goes to the heater core has a spring assembly in it. It is in bad shape and in need of replacement. I broke out all the remaining pieces and the spring so the debris won't go through the cooling system if I have to use it. If not available I guess I'll find out what effect not having the assembly in the steel nipple will have on heat come winter. Part number for the steel nipples and o rings that go on them would be helpful. ]]> Pontiac obe https://www.gmforum.com/pontiac-168/1999-bonneville-belt-tensioner-questions-315653/
