I'm hoping one of you Jeep vets out there can help shed some light on a topic for me.
I have a 95 Grd Cherokee w/ the inline 6 cylinder. It idles rough, and has stalled in the past. The local dealership says its the Idle Air Control that's gone bad and is causing the problem.
When I run the self-diagnostic on the Jeep, I get codes 12 and 17.
I belive code 12 is:
"Direct battery input to PCM was disconnected within the last 50-100 key-on cycles. "
and code 17 to be:
"Engine did not reach operating temperature within acceptable limits. Engine does not reach 20º F. within 5 minutes with a vehicle speed signal."
Can anyone out there shed some light on what these two codes mean - and more importantly, what is required to fix them myself (if possible).
I can't tell if these codes are related to the IAC like the dealer says. What would be causing code 12 and 17?
Any help would be greatly appreciated. I'm hoping that I can do this work myself in the coming weeks.
