03 ram tps

[minneman]

this lite has been coming on more frequently in the past year and causes the truck to go into limp mode, and now expect it to happen daily, or every other day. easily fixed by pulling over and restarting. It seems ive heard of issues with this, true?its a 5.7 - 2500.

any known servie bullitens with this problem?

easy fix?

I would assume your talking the check engine light? Is is throwing codes after this happens? TPS would be throttle position sensor.

To find out turn the key on-off (not to the start position) 3 time and codes should flash on your odometer screen.

TPS would be throttle position sensor.

Correct 311, the engine lite is on but throws an evap code, i assumed it wasnt part of this issue.

The red lite that comes on is on the right, a lightning bolt in parentheses.

That would be the light for the electronic throttle control.

I'll do some digging when I get into work tonight.

Looks like there is a TSB for a PCM update for the ETC system. Depending on your current software and the codes/problem you are experiencing that may be an option.

[minneman]

Thanks airjer! i'll be checkin into it.

If a re-flash doesn't take care of it you may start looking at the wires up towards the fire wall to see if any of them are chaffing or wearing through and ground out. Seems I remember reading about someone having a similar issue with the ETC light coming on and they found a wire that had worn though the protective coating.

Good point, I have had some issues with mice/chipmunks in the past. seems odd that it's progressivly gotten worse over the last couple years, which sounds more like a bare wire happening than a software issue..?
