Hello,
I have a 2004 F350 with the 6.0. Recently lost all throttle response. I changed out the accelerator pedal with the built in sensor. When that didnt work, ichanged out the throttle position sensor and reset the pcm. Still have no response. It starts up fone, idles good and when i put into gear, it moves but at an idle. No codes being thrown and no lights on the dash. Any suggestions on what to check next work be appreciated. Thanks!

 

What are you using to read codes (not all code readers are the same). I suggest getting the Forscan app for your phone or the full program for PC's. Pair it with an OBDII dongle (Bluetooth for Android or WiFi for iOS).

Watch your ICP, ICPv, IPR%, pedal position sensors (should be 3 IIRC), FICM MPower, FICM LPower, Fuel Pulse Width, & VREF V PID's. Post all PID values KOEO and while driving. Let us know what you are doing to your skinny pedal at that time when you post the values. Would be nice to know your fuel pressure as well, but that would require an aftermarket sensor.

It's a pretty basic code reader. I'll look into the ones you suggested and try those

 

Forscan Lite is $5.99 on your app store(Android only) You can get a Bluetooth Dongle online for anywhere from $25 to $45. Torque Pro is fairly good product to, But Forscan is pretty much the best code reader for a 6.0.

 

Got the Forscan. Dongle is on order and should be at my local store in a couple of days.

 

We don't expect that you will regret the moderate expense. Your willingness to take this advice based on our experience is appreciated.

 

Once you get it and use it, you'll kick yourself for not having it earlier!

I suspect your HPOP might be shot. The symptoms are similar to my experiences. So, I’d do a little research if I were you to confirm or deny that’s the problem.

I’ve had two 6.0s and had to do the HPOP in both. I’ve installed the Adrenaline pump in both trucks and cannot say enough nice things about it.

Edit: FWIW both my 6.0s were ‘04s. Probably doesn’t mean anything…
