Total loss of throttle response
41 - 60 of 67 Posts
Here is an update to my issue so far I have not seen the issue again. Maybe it can help someone else.
After replacing the MAF, the mech re installed the monitor recorder. Monitor all PIDS for acceleration and found Brake Override Action at 27. Monitor BOO1 and BOO2 , after 100 miles of driving found BOO1 was very touchy. BOO1 was coming on without touching the brake pedal. With BOO1 on engine was overriding the accelerator and causing the problem. Replaced Brake Switch and road test and monitor all PIDS. All passed.
Like i said so far I v not experience the issue again, but will continue to monitor.

My 08 F350 SRW 6 speed manual is having same issue. When I shift from 1st to 2nd it fall on its face and the rmp's drop to idle with no throttle what so ever. Just bought truck yesterday. Has all deletes done that I know of. First powerstroke to own. HELP please!
My 2013 F350 SRW 4x4 (purchased new in 2014) has been experiencing throttle loss numerous times, and been in dealers a dozen times with only the result of "cannot verify".
It happens after braking then throttle is lost for an extended period when trying to accelerate. (Single foot drive) When braking when traffic decides to nearly stop, release brake then turn into vacant lane, then find you are then powerless in the new lane when trying to accelerate to traffic speed before you are now an obstacle to the upcoming vehicles. Or slowing to make a left turn in an uncontrolled intersection and after you are committed in turning across traffic to find you have no throttle.
Now, I do not change lanes when having to brake for traffic. The last time it happened I timed over 10 seconds before the throttle reappears. 10 seconds was timed after I realized the throttle was lost and then the decision to start timing.
The throttle loss, the wipers doing a single wipe frequently only when starting the vehicle (no rain sensor, courtesy wipe set to off), losing the command button function during trips or several days at a time, other Sync/radio related issues one being losing all sound to the speakers though volume control is showing on the display, makes the 62k truck in dire need of an exorcism.
Dealers state no abnormal data in override pids.

Hi RwL_SoCal,
When you were at the dealership for the throttle concern, did you take your tech on a test drive? How many miles are on your truck currently? I want to do some digging and see what I can do to help with all of the items you mentioned. Regarding your SYNC issue, I recommend reaching out to my colleagues on the in-vehicle technology team. Here's a link to their profile here on the forum: Diesel Forum - TheDieselStop.com - View Profile: FordIVTteam

We had a ford tech come down and after I used a monitor to record it when it happen, they said it was one of the two "Brake On/Offf Sensors" that was bad. They replaced that sensor and I have not had the problem again.
Unfortunately this weekend. coming back from a rodeo I worked at, the truck again decided to become an obstacle in the traffic lanes for other motorists. Fortunately, no one collided with my truck or others in avoiding me. I have decided the truck is not safe for me or others on the road.

6.7 Loss of throttle response at speed
2014 6.7 F450- 45000 miles on it. Transitioning from one freeway to another, curvy underpass about 50 MPH- Truck loses throttle response, engine goes to idle (600 RPM) and speedometer goes to zero, all while moving about 50 MPH- Traction control light comes on for a few seconds, then goes out. I have to pull over on the shoulder. Engine continues to run at idle during the entire event. I'm about ready to shut it off and "reboot" it when it suddenly responds to the throttle and off I go. About 300 yards later, same thing. Same traction control light for a few seconds and zero on the speedometer, even though I'm moving about 40 MPH. This time when I get pulled over, it starts to function correctly again and I'm back on the road. Have a service appointment at the dealer in 2 days. They thought I was losing it when I described the event. We'll see. Haven't had a lick of trouble out of the truck until this. But it could have been bad-I pull a 53-ft. race car hauler and that can get real testy losing power with that thing behind you.

Welcome to the forum, Fuelish Habit. I'm glad you'll be getting the truck into the hands of your dealer; be sure to come back and tell us what they find. I'll be here if you need any help after the appointment.

Just finishing up at the dealer. They have no answers since it can't be duplicated in thevtestbdrive they did. No codes, active or pending. So right now I'm out $190 and have a truck that I don't trust. A $75000 truck!
Same here. Dealer in St Petersburg FLorida has had my truck 4 times. It's like they think I'm nuts.
Doug C,
This is what eventually fixed mine and I have not had a single problem wit it. Truck has 54K miles on it now.

Welcome to the forum, Doug C. I'd like to see what I can do to turn this situation around. How many miles are on your truck?

I have the same issues. In fact it sounds like you have my truck.
Throttle/Power loss from start. Example stopped at a light to make left turn. Truck acellerates normally for a moment then in the middle of the intersection drops to idle, then recovers. Numerous times to the local dealer. Been in a loaner for 9 days. Now they say they cannot duplicate concern. Just called Ford. Let's see what they have to say.
Wipers come on at start as you describe. Replaced Multi-function switch 2 times.
Radio-This was actually corrected by an outside vendor finally. Sirius did not refresh upon start and no sound. Required radio of then on to operate. Again, they thought I was crazy.
60 plus thousand for this truck- Perhaps I am.

Case number is ........0308. Been in a ragged out loaner truck for 9 days now.

Thanks. Spoke with another local dealer with more diesel techs and they suggested I contact Ford. So now at least I have a case#.
