Final verification
: A faulty card or sensor inside the tiller unit can send inconsistent analogue signals, triggering the "implausible" status.
To help narrow down the specific fix for your machine, please provide a few additional details: Is the error code or intermittent ?

If the error persists after replacing a base sensor, the pallet jack may require calibration. Using a Jungheinrich diagnostic display or diagnostic software (JUDIT), a technician can reset the "zero point" parameters for the tiller travel zone. Prevention and Maintenance Tips
The default window assigned by older firmware versions to recognize the neutral steering and control position is incredibly tight. Normal physical wear over months of operation can push the analog signal slightly out of this tiny window, triggering an "implausible" sensor reading. 2. Physical Wear and Debris
: Jungheinrich has identified this as a software-related fault where the "window" for the neutral zone is too narrow. Final verification : A faulty card or sensor

If you'd like to narrow down the problem further, let me know:
Disconnect the main battery plug to drain any residual voltage from the capacitors. Wait 60 seconds. Reconnect the battery and power the unit back up. triggering an "implausible" sensor reading.
Regularly lubricate the tiller arm pivot pin during scheduled preventive maintenance to prevent mechanical binding that strains both sensors and wires.
