dead pedal on 2008 hino..

junkpickup · Jul 14, 2020

My 2008 hino just had lots of work done. New injectors, new dpf filer, new fuel pump, and new suction control valve. Despite all the work done sometimes when the truck is in park, drive, reverse or neutral and you hit the peddle nothing happens. It won't rev the engine. It will move if in gear but only at idle. After a few trys it goes. Can be dangerous at intersections. I spent a lot of money getting this fixed and it still does not work. Any thoughts or help would be appreciated..

Thank you..

That really sounds like a brake switch problem. Air or hydraulic brakes?

It’s air brakes.. There is another thread with similar issue. I’m going to look over that. I’ve been tracing wires from the brake switch but can find no nicks are damage. The rear speed sensor wire is damaged so I’m replacing that sensor. Would that cause this issue?
thank you Greasy
