Yes it sounds like the pot for the tilt, if it was the motor sensor I would expect the fault to occur during lift and side shift operations also.

Hi Roi! Jungheinrich EFG 500, S/N: FN417274. I have a new observation, the hydraulic motor pump RPM is slow when activating the tilt cylinder compared to Lift Function. I guess its the Solo Pilot Potentiometer for TILT command. Please note that lift is normal.
