Re: idle fine, dead pedal when SES light on, light off- everything fine
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: clippercliff</div><div class="ubbcode-body">2001 F350 7.3 starts fine every time. Idles fine. Service engine soon light comes on; still idles good but accelerator is dead. SES light goes off and I can rev engine fine. Read a bazillion forums and changed the EBP tube, EBP sensor, gutted the EBP valve at the turbo and unplugged the two wire sensor there. Nothing, notta, nill...still having same problem. Can't stealership or shop it as I pull a trailer daily with my construction co in south Louisiana.
What's my next suggestion or step?

X2 with ACTION get code.
TPS assembly is most likely faulty and the IVS is sticking.
IVS (idle validation switch) tells PCM "no pedal we are idling"
press the pedal and the switch don't say "PCM time to go!" so it just sits there thinking you still want to idle.
IIRC you replace the pedal assy, about 125.00 to your door.
Some have wd-40'ed the switch and loosened it up, worth a try!
it's on the pedal bracket, easy to see!
