Not sure what to look for on this. The truck normally would stall out after a few minutes with a loping idle. You could feather it to keep it going. I was thinking it was a sensor Cam, IAC, something like that. Seemed like it (the truck) wasn't sure how to idle. You could always just restart it.
Today however, It stalled while under thottle (gas pedal depressed) going down the road. And would not restart. It would simple turn over and over and over... Nor aparent firing. 10 or so minutes after trying to restart it the battery went dead.
We had it towed (Thank god for AAA) and are awaiting it to be delivered (140 Mile Tow).
What should we look for. What would cause the truck to stall and not restart when it normally would restart with no problems?
Yes, I am positive as I stated before if it stalls in a position where there is an intake valve open gas will come out the intake manafold as it has no other place to go.
What do you know about:
AUTOMATIC RESETTING SOLID STATE TYPE - PTC
A Polymer PTC (for Positive Temperature Coefficient) is a special type of circuit breaker called a thermistor (or thermal resistor). A PTC thermistor increases resistance as its temperature in increased. PTCs, which are made from a conductive polymer, are solid state devices, which means they have no moving parts.
These are in the wiring of the truck and I honestly just learned about them after looking over the wiring diagrams for the truck and looked them up.
This sounds very promising as the issue is temp specific and I first thought it was engine temp specific, now I don't think so. We had the truck run for 22.5 minutes at this point it had gone from open loop to closed loop and was still running.
I am strongly thinking its an issue with the coil circuit and due to bad wiring within that circuit this PTC shuts the circuit down, stopping the truck from firing. The PCM never gets that message until the PTC cools down enough to send that signal to the PCM.
I've never heard of or encountered any such thing in Dodge wiring and my factory diagrams show nothing in the coil driver circuit. Are you still getting the intermittent CKP code? I'm thinking once it gets hot, the signal is breaking down.
Yeah, the gauges no longer freak out, it no longer stalls, and at tempereture fuel system primes as normal.
The only issue now with the truck is the abs light, speedometer not working, heater blower only blows on high. Ill should make a new post for that I think.
Heater blowing on high can be attributed to the blower motor resistor going bad. Simple, inexpensive fix. Make sure the plug isn't melted as well. As for the ABS, start by scanning the module.
I've never seen them before, but judging by the diagnostic chart, you have a bad ABS hydraulic control unit (HCU). 63 is set by an internal fault with the HCU and 82 can be caused by the 63, or by the incorrect axle being programed into the HCU.
I believe it was but axle ratio is irrelevant to this code because the number of teeth on the tone wheel will remain the same. If the PO installed something like a 10-1/2 and didnt reprogram the ABS accordingly, then you'd get this code.
