Dead Gas Pedal

I was driving my '16 Transit 250 (3.7L gas) down the highway, cruise control on, when out of the blue the cruise kicks off and my gas pedal goes non responsive. The engine was still running, and I was able to get to the side of the road, but the pedal was dead.

Check engine light was on, as well as a yellow "i" light in the bottom center of the dash, along with a written warning on the LCD saying something about the engine and having it serviced.

I shut the engine off and it sputtered out. I started it and it fired right back up, but the engine wound up to almost 3k RPMs for about two seconds before settling back down to a rough idle. Gas pedal was still dead.

I shut off and started a second time, to the same effect. Rev high, settle down, idle rough -- and no pedal.

As I'm going through the menus for Ford's roadside assistance, I decide to try the van again. It fires up, no rev, and idles like normal. Check engine light is on (the little yellow one shaped like a motor), but the gas pedal works and when I hang up and pull out onto the highway, the van drives like normal.

I drive roughly 75 miles this way, no issues, other than the check engine light being on.

I park it overnight, get up this morning to take it to the stealership, and not only is the check engine light off (the van started normally), but the engine seems to have more pep. It's been running like a dog, especially on hills, for a while now -- but it drives like new this morning. No warning lights, no sputters, no revs, no nothing. Drives like the day I picked it up.

I've had the van for just over three months, and have put 9,700 miles on it.

My question is: what gives? Is it just a computer burp? A TPS acting up, maybe? I couldn't leave it at the dealership because it's my only car and the junk third party warranty I got scammed into buying (without realizing it until today) wasn't accepted at the dealership nearest me (not where I bought the van) -- so they wouldn't give me a rental car. But the van is running fine, and I'm wondering if I need to even bother taking it in?

At least have the codes read. If it is throttle body you WILL want to get it repaired. See other throttle body posts.

Would a throttle body act up like that?

If the Throttle Position Sensor (TPS) is having issues, then the PCM doesn't know how far it is really opened and/or if the motor controlling the throttle itself is having issues and not properly responding to commanded movements... sure, those symptoms seem reasonable.

For example, say the throttle plate needs to be at 14° (0° being closed say) for idle. The TPS is reading inaccurately and reports 14° but the throttle is really at 30°. This would cause more air than is necessary for idle and thus higher RPMs.

Makes sense. I think, for some reason, I had the TPS and Throttle Body as two separate things in my head. Derp.

I've got to straighten out the warranty first, but then I think I will take it in. Just to be safe. This is the first issue I've had with it, and it's kind of shocking at < 10k miles. In my mind, there's no reason why a brand new vehicle straight out of the factory should have ANY non-driver-related problem in the first 50k or 60k. :/

As an update, I've put about 500 miles on the van since the dead pedal incident, and the van runs great. No warning lights, no rough idles, starts every time I turn the key.

The problem I'm having now is with my warranty. One dealership (closest to me) says that my extended warranty (the warranty beyond the standard 3yr/36k) is from a third party warranter (National Vehicle Service) and they (the dealership) don't accept those...while Ford itself assures me that it's a Ford warranty and is good at "every" dealership in the US and Canada.

Anybody ever had this problem with warranties? The dealership I took the van to would work on the van (because of the 3yr/36k), but wouldn't give me the first day rental car (because it was part of the extended plan).

I had my throttle body replaced at 6800 miles. Died on the freeway at 70mph. I
thought it was freak thing but happened again a few hours later.

Part is nationally back ordered. Took 3 days to arrive. Dealer said it was common on 16's.

There needs to be recall.

Not an expert, but, I don't think ANY of that extended service plan stuff is good during the normal warranty period.

Really? Wow. The van is my only vehicle (we're "van dwellers"), so not having first day rental is out of the question.

The more I think about it the more I think I need to just trade in my Transit on a class C Sprinter-based RV. :/

Van broke down again today. Drove it to the dealer, they replaced the throttle body. So far, it's running fine, but it was lucky the dealer had one lying around. They said there was a 3,300+ backorder on them.
