Help.

The story. My HPT usb cable fried when programming so I had my ECM sent off to be reflashed. It came back the car runs fine but the pedal doesnt do anything I have checked all the fuses. Is there any module or something that I may have missed?

I did unplug the star connectors and all the modules i know about, even took the ECM down twice to reseat the connectors. No response still.

Fuse 17 is good. Is there anything else related to what may be causing this. Also when I crank it up the Throttle body cracks as normal so voltage is getting there.

 

Thanks in advance

 

Have you checked the DIC for codes?

History data

 

No codes I can see tell me anything.

Anyone have any other ideas?

 

maybe TAC module?

 

On many drive by wire cars the throttle will NOT respond IF you have messed with the " ETC TQ. limit reduction table "---many tuners will set this whole table to 100%--this usually eliminates the no throttle---BUT be careful the opposite affect would be the throttle will "hang" WOT for a few seconds after lifting----Then i back off the 100% setting to around 1/2 way to the end----there may be other tables in the same file that affect the throttle as well--they are all found in the "traction control " section
