no throttle response

[bobsundance]

I have a buddy has a 1999 ford F 350 diesel. the engine runs but when you give it the gas nothing happens and the check engine light comes on. When you let off the gas it goes out and the light goes off. Any ideas or how do you get the codes without a decoder?

Sounds like the throttle position sensor is bad. Have to replace the throttle pedal assembly to fix.

HAD SAME PROBLEM, FORD WANTED 185.00 WHOLESALE PRICE FOR ONE. I BOUGHT A DORMAN PART#699-201 FOR 49.99 IT IS JUST THE SENSOR , NOT WHOLE PEDAL ASSEMBLY:

I had a simular problem with my 01...However, mine was due to a short in the wiring harness in the columb . The shifter(automatic) fits into its hole in the columb and has a hardened pin that keeps it from coming out. This pin is held in place by a steel clip. The wiring harness for the overdrive button crosses this clip and continues up the shifter to the button on the end. When it is shorted to ground the fuse blows and you loose your glow circuit, gauges, and you guessed it, Your pedal. Idles great.... Dealer wanted $ 150. to look at it and was told by a freind/ford diesel tech that all they would do is sell me a columb....sigh....3 inches of heat shrink, 5 inches of 3m electric tape and one tyrap. .87 cents

Do you have the other symptoms of the gauges also? Looks like good info, if no
problems with other stuff, then could just be the pedal assembly switch.

I had the same thing happen to me.

To the OP. Check your fuses and see if you've blown a fuse, that will help diagnose it.
