Accelerator pedal not working

Last night I stopped at a red light. When the light turned green I pushed the accelerator and nothing happened. The RPS didn’t go up at all. I idled into a parking lot to get out of traffic. When sitting there the RPMs slowly started to climb with me not even pushing the pedal. If I pushed the brake pedal they would drop. I tried revving up in neutral and nothing. I put the truck in park and killed it. After a few choice words I cranked the truck up and it started working like nothing ever happened. I drove it home last night with no problems. I was just wondering if anyone had any ideas on what could have happened. I don’t want to get the truck on the Highway and this happen again. I did check all my gauges when it happened and nothing was out of normal operating parameters. The only mods to the truck are straight exhaust with no regen. System and SCT can tune. Any and all help welcome!!!

That's one of those problems that can be anything. Could be a bug in the tuning code, could be a bad accelerator pedal, could be a wiring harness issue.

Good luck man. I would be nervous too if that happened!

I have read of this before and it may not be the fly by wire pedal being a problem
the reference voltage is shared by some sensors in the exhaust as I recall and it was a problem with one of those wires that sends the truck into a limp mode of Idle or just above normal idle
just going off of another few post however

Yeah, this is one of those problems that would require a bit of magic to diagnose without Ford's IDS tool. Might be a bit easier to take it in and have a diagnostics done. Then just tell them you'll fix it yourself.
