Any Dodge or Ram techs I need some help please. I was driving my 2004 Ram 2500 with 5.7 hemi to go to one of the Mopar clubs car shows today (I call it the to broke to go to the Nats show) and stopped for a stop light. Upon accelerating when the light turned green my truck died, as I was costing to the shoulder I noticed the ETC light flashing. I tried to restart and nothing but I noticed all of my gauges were down to zero except the volt gauge which was higher than normal then it to would drop to nothing and the outside temp was showing -40 when it is really about 80. Called for a tow to get it to the shop I work at. Hooked my scan tool up to find 12 codes 5 of which were pending. Most of which are showing circuit high input for 5 different sensors, and some crazy things in the freeze frame data such as ECT at -40, spark advance at -64, IAT at -64 TPS 100% and Vehicle speed at 158 mph. I am a Ford diesel tech, and my friend who works at Dodge is out of town. Any input /ideas would be appreciated. As much as I lke driving my Super Bee, I do not want to drive it to work every day until he gets back. Thanks

Any other ideas?
What codes does it have now after the battery disconnect?

etc light is the throttle body and when they puke that's the codes you get.The power and ground for several components run in series on newer trucks.

Unplug the crank sensor and see if the affected sensors start reading right. Have had those in the past short out and cause all kind of no start and no communication issues. If that's not it start unplugging one 5v sensor at a time and go from there. Does your scanner comm over the PCI bus or generic bus?

Ok, I borrowed a friends good scanner and with it it brought up even more codes, they are as follows P2016 ETC force limited power P2111 ETC stuck open P060B ETC A/D ground performance P2167 APP sensor 2 max stop performance P2116 APP sensor 2 min stop performance P2128 APP sensor 2 circuit hi P2123 APP sensor 1 circuit hi On data it shows throttle position at 133% but the blade is closed.

Todd is correct as its easy to forget about the pedal unit. It has sensors that tell the PCM what pedal posistion the driver wants and then the PCM will work the throttle body motor to move the throttle where it needs to go. The throttle body is not cheap and your best bet would be to have a shop diagnose it to be sure what it is. Not trying to be smart but you really need to know what your looking at to diagnose it right and not replace the wrong part. When I get one with alot of codes I pick one that makes the most sense and then diagnose that code which will usually get to fixing everything. I just dont want to see you replace the throttle body if your not sure thats it. Its tuff to try and diagnose over the internet. With the scan tool you can read the APP sensors and the TPS sensors to see just what is going on and you can acuate the throttle body motor to see if the PCM can comand it. Ron

What do the APP sensors read when you move the gas pedal with them hooked up as they should change. 5 volts at rest does not sound right. Ron
Sounds like its time for a new pedal. The voltage on sensor 1 goes in the opposite direction than sensor 2 does when the pedal is depressed.

Could that cause IAT,ECT,Ambient,fuel sensor A all to read 5V ?
Get out your manual and I would start with an easy sensor to get to like the IAT. Disconnect it and ground the signal return circuit. Look at the scan tool and see if the volts go to zero. If it does there is a problem with the sensor. If it stays the same, back probe the same circuit at the pcm connector with a T-pin. May have an internal problem with the PCM.

I started doing the pinpoint tests for the high voltage codes and so far it looks like a PCM. I have a few more to try. Thanks for the help. Being a tech even though its Fords,I hate to send it to someone else.

Put the new PCM in today, let the throttle body reset, and it fired right up. Overhead still reads -40 but ambient on the scanner was reading right. Do I have to reset the overhead somehow? Thanks for all the help on this.
