Loss of Throttle/Accelerator

[Midlojoe]

I am at my witt's end! I have a 2005 F250 6.0 PSD. it has a banks 6 gun (disconnected for now) EGR Delete, and new oil cooler. I have also done a head gasket job in the last several hundred miles but less than 1000. a couple of times it has given me a SES indicator and lost throttle control. the codes I am getting are P0237 and P2285. I took the turbo apart, cleaned it up and re-installed to no avail. It did not look all that bad and was not sticking but did have a little carbon build up. I have also replaced the MAP sensor, The ICP sensor and pigtail and the Accelerator/TPS module. Can anyone give me another direction to look. I have also been through the wiring harnesses looking for shorts, grounds or bad wire and just cant seem to find anything.

Well chit you changed all the parts that would be suspect for the dead pedal in My book

I would go through connectors and check them


sorry can't Be more help

Bump

just to clarify the TPS module is part of the pedal assembly and is replaced as a unit

correct

[ZMANN]

it sounds like he may not have replaced the whole unit by his wording??
so I was clarifying what He had done but the ICP harness when failed on mine was a dead pedal so and is his code is a ICP code anyway

otherwise a TPS would refer to a reference voltage out of range code IIRC

The come as a complete unit when you buy a new pedal from ford, so he must have??????????

It is a complete assembly on the 05. As far as wiring, I have checked back into the harness several inches from where the pigtail on the icp ties in. There is no pinches or crimps along the entire harness. Another question I have is what codes will come up for the ebp sensor and will it cause a dead peddle?
