2004 dodge ram hemi: I get the throttle body warning light coming on when the truck bounces on rail road tracks. If I shut the truck off and restart no more light any solutions.

I think this means your electronic throttle control (ETC) has a problem. The ETC takes the signal from your accelerator pedal to control the throttle plate in the throttle body. See this link:

Sounds like the ECU. Have you read the diagnostics codes yet? Do you have a check engine light?

Hi Dolph, Take the vehicle for a diagnostic scan. I suspect something wrong with the air flow sensor or mapping sensor. Regards John

Quite often just a good cleaning of the throttle body will cure this code.

The 5.7L V-8 engine does not use a seperate TPS on the throttle body

Sounds like loose earth connection,or connection that is not making good contact best to have it checked before it causes more issues.

I had the same problem with my, 03, hemi. I did not wait 15 min. turn off and back on was all that was needed to reset, "red flashing light lower right hand ". though another 8 or 9 on off's, Engin Light also goes off, untill next time. All i did was pulled off my Air Intake box and hose, so i could get to butterfly on throttle bodie, sprayed carb cleaner in there. and it was very dirty. after put back togather, give it a few.... mine did not start right up, when it did idle real ruff even died few times...Once the computer re adjusted ran like it did when i bought it....that was 2 weeks ago, still no eng light, no flashing red ones either.

sounds like u might have a sticking valve. i do know that they have had alot of valve problems with this motor

Take throttle body off, clean Throttle Body with Carburator cleaner. I had same problem and its the ethynol in fuel that creates a build up in the throttle body which creates this problem. I did what a friend of mine said to do (service manager at Dodge Dealership) it hasnt happened again.

I took my 2004 Dodge Ram 1500 5.7L Hemi to a mechanic that works from a garage at his home, recommended by a friend of mine. He removed and cleaned the throttle body and sensor(s?), then reinstalled them, and then disconnected both battery cables and held them together for 2 minutes so that the engine controller could reboot with the factory default settings, then reconnected them. I had bought a can of throttle body cleaner on my way over to his house for about $3.00. He charged me $40.00 for the job. This was done mid-February, about 10 weeks and 2500 miles ago. So far, the problem Has Not happened again, the truck has been running great!
