I was on I-85 between Georgia and South Carolina. Speed Limit in Georgia is 70mph and S.C. is 65. I was using my cruise control set at 75mph crossing intoS.C.I cut the cruise control off due to the heavy traffic and reduced speed limit. I traveled about one mile when I noticed the truck was slowing down and the acclerator was not working. Ipulled off as far as I could get on the shoulder of the Interstate. The acclerator pedal had no control at all,laying against the floor. I had the trucktowedand the garage told me that I had lost power which caused the problem. They said my battery was the culprit. They stated that their dignostic showed the battery was completely(?)dead. Ihad the A/C on and the head lights. After stopping I turned my emergency flashers on and they worked fine. I have never heard of this, could the battery cause this problem? ---

You didn’t tell us the age of your truck. Yes, the battery could cause this problem. How old is your truck? ---

The throttle position sensor sends a voltage to the ECU relative the position you set with the pedal. The reference voltage for the sensor comes from the ECU I believe so it seems more than the accelerator pedal would have been effected if the battery was dead. There may be a wiring problem to the TPS sensor and if so a code should be set to warn you of that. I assume that whatever caused the low battery charge has been fixed and perhaps it may clear this trouble up. ---

Truck is a 1998 Ford F150. the mechanic finally came clean. I told him I did not belive it wasthe battery because I started the Truck twice after the accleratorstopped. He stated that the wire had pulled loose due to my floor mat riding up and hanging. this was after I had paid him for the battery. ---

The truck is a 1998 model. It was a wiring problem. After selling me a battery, and several questions,he stated that the wiring had been pulled loose by the floor mat.
