I recently replaced some components on the drive board for the hydraulic pump (lift pump). After getting the forklift operational again, I now have a code 91 (pump motor temp high). I have read that the sensor could be grounded or bad. Does anyone know where the sensor is located? Or if there's a way to bypass? The motor is definitely not hot, as it is displayed immediately after turning the key on. After operating the forklift for over an hour, the motor is still not hot and nothing seems to be affected by the fault code, but I believe I am unable to change to the modes while this fault is active.

Any help would be greatly appreciated
