Hi there, does someone know what is D-75 troubl6 means ?
My unit mode # DP50CN1 S/N AT19E80073.
It's working good, and some time the accelerator pedal inoperative, the RPM won't go up at all, then I turn off and turn engine on again to reset. Can someone help me please ?

I know the OP posted this a long time ago, but with the recent bump, here goes...
D-75 on these perkins dp50s is usually related to the idle validation switch not switching at the correct time relative to the throttle position ramping up.
I've found its usually either a bad idle validation switch, shorted wiring leading to it, or just mis-adjusted.
The pedal sensor voltage should be about.35vdc at minimum thither and the idle validation switch should be closedat this point, but open with any throttle input. It can take a few tries to find the sweet spot if you don't have the perkins software to view it while adjusting.
I have been looking at this for a long time, and no one seem to find anything to fix this error code. I have your same model forklift and i am going to change the throttle position sensor. I think is that. I will advise. In the mid time, have you found anything on it?
Did you ever get a response to your question or did you figure out what the problem was? I have the same code and symptoms.
Helloooooooo,,, some body there ???
