OK. Here's my situation. Yesterday (11-9-10). I drove to my job no problem. Then when leaving to go home. When I try to start. It did nothing. Light and electrical seem OK. But the gear selection indicators are all lit. OK, I say. Maybe the battery cable, terminals are dirty again. Always have an issue with this. I clean them as good as I can. I go back inside. I start it. Starter operates now, yippee! Then it starts to act up BADLY! The speedometer goes haywire. The engine started up then it just stopped running. I attempt to start again. Does it again, runs for a few seconds and stops! (Never happened to me on this van). THEN out of the blues, the van cranks but now does not start at all! I had it towed to my house. While working on it a little. The check engine light FLASHES. And suddenly I get 6 codes all at the same time. ALL of them to do with "low input voltage. THESE are the 6 codes, for which 3 of them are manufaturer default codes.

P0122 throttle/pedal position sensor A ckt low input
P0117 Engine Coolant temp ckt low input
P0107 Map/BARO crt low input

and the manufacture codes
P1478 battery temparture sensor out of limit
P1496 5 Volt supply output too low
P1192 Inlet air temp sensor voltage low

ALL to do with LOW voltage...... hmmmm. If I'm getting all those similar codes. To me that sound like just ONE big thing broken. Sounds like the computer is shot. Am I right???

Oh BTW. Today, I really took the time to CLEAN out all cables, and even replaced one. So as of now. I charged the battery. Its no problem here. All electical is OK. windows, locks, radio, all lights, everything. The instrument panel however, the speedometer needle is pointing to the "other side" Like if it's past 120mph!!

Also I connected the battery to obtain the codes. The van passes those codes immediately even if I disconnect battery and erase codes.

Have ANY of you have a problem like this?? I would love to have your input about this! THANKS

 

Are you SURE that NO ONES KNOWS WHATS GOING ON with my van???? Im VERY surprised that no one knows about this. I hear this type of thing is FAMOUS for happening on these Caravans. Surprised NO ONE knows!

 

IM very surprised of you guys. You cant even give info about the most COMMON problem on these vans.

Well anyway It was INDEED the ECM. I had taken it to a shop to comfirm this. Where they did complete testing. And to be sure that it was not something else thats bad that possibly shorted out the ECM.
Well anyway. The ECM was $310 total at Kragan auto parts. And $350 (incl towing) to put it on... ****** those mechanics are. $300 for just 2 hours of their time. (What goes around, comes around, and I hope they get it soon) I knew from start it was ECM. But wanted to make sure. And man, I paid the price! BUT anyway, it was $650 total. Dealer wanted $1000+ for just the part! Forget getting ripped off a little. IM JUST HAPPY MY VAN IS RUNNING AGIAN!
