So i have searched this and gone through a bunch of post... but i was hoping someone could help me with this.

My wrench light came on and when i pulled the codes that's what they were, the odd thing is that the truck runs just fine. i have only found one post where the truck ran fine and it turned out it was a clogged hose between the manifold and the map sensor. i have check it and in my case it isn't clogged.

Anyone else have any suggestions?

I'm going to check and make sure there are no chafed wires but other than that i don't know where else to look. I'm having a hard time thinking its the pedal or the pcm if there are no signs of anything being wrong other than the light and codes... then again im sure it can be wishfull thinking.

Thanks in advanced.

BTW... its a 2006 f350 drw cc long bead with 75,xxx miles.

 

look like its a throttle position sensor or something

P2122 Throttle/Pedal Position Sensor/Switch "D" Circuit Low

P2138 Throttle/Pedal Position Sensor/Switch "D" / "E" Voltage Correlation

P2139 Throttle/Pedal Position Sensor/Switch "D" / "F" Voltage Correlation

Depending on what you're reading codes with you may or may not be able to read the wrench light codes and I'm not sure pedal codes will activate the wrench light.

 

Blade35, those are the codes... 2 months+ later its still on... I have ordered a new pedal ike just waiting to get it in the mail. I have looked arround for chafe points but I'm thinking I will have to pull the harness in order to make sure.

Once in a while in the mornings the light will stay off for the first 5 or 10 miles then come on.

I am woriried though that if there is a shorter wire it will fry the new pedals circuitry.

Anyone ever found a aborted wire and not had to replace anything?

 

I don't think the pedal codes will cause a wrench light and not many code readers will even read a wrench light. What are you reading codes with?

 

npccpartsman:

i borrowed a buddies code reader to verify my readings with my edge attitude. those three codes are the only ones that come up and as soon as i clear the codes the wrench light goes off...

as i said earlier ill leave in the morning with no light on... ill clear codes and 5 or 10 miles later the wrench light comes on and the codes come up...

Is there a reason you think that the pedal codes wont turn the wrench light on???

 

Will the edge show you accelerator pids???

I think the SGII gets 1 out of 3 total pids for acclerator pedal position

How about accelerator pedal %

I have some stuff on it but wont do you any good if you cant see the pids

Beeen trying to get the info on here but wont let me

you might could backprobe at the pedal with a DVM everything basicaly comes down to a volt reading the PCM reads it with

if you want PM me your email and I will try that way to send it to ya I just cant get it on here Im not computer smart

 

I'm not sure what pids are so im going to say that the edge doesn't show them.

It does show accelerator % and its smooth from idle to wot. I'm guessing if it is a bad pedal it must be reading one of the signals that's still working.

can you enlighten me on what pids are and maybe point me in the right direction as to what i need to see them... ill have to call in a favor or two to get my hands on the right equipment.

 

this first code is the one thats causing all the Havoc Id go over that harness really good

A pid is like your EOT reading on that edge

OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool

 

If you cant find any defect in the harness then check for continuity from acc pedal to PCM

Im not shure what pins at the PCM that you will need to check for continuity maybe a tech will chime in or you could PM Cheezit or M-chan about it

It maybe the case that you need a new acc pedal but there spendy I would only go this route if all eles failes

 

Here is also a link to the 6.0 wire diagram

https://www.ford-trucks.com/ford-man...%20diagram.pdf

Looks to me like a 3 track pedal with 2 V-Ref signals to it

Can you check referance voltage with that Edge

If not that V-Ref signal should be 5 volt signal to it and looks like theres 2 v-ref signal you can make shure your getting that when you backprobe the pedal with a DVM

 

Blade, Thanks for the advice...

now...

Anyone know where i can get a wiring diagram for our trucks? I'm going to be tearing the top off the truck soon to replace a leaky egr cooler so i figured that would be a great time to go through the harness with a fine tooth comb...

 

Wow... your feeding me information faster than i can read lol...

Thanks Again

 

I posted a wire diagram in my last post

https://www.ford-trucks.com/ford-man...%20diagram.pdf

wire diagram^^^^^^^^^^^

 

I hope your planing on a Oil cooler to with that Egr cooler
