Jungheinrich released an official engineering bulletin acknowledging that the factory neutral-zone tolerances on certain EJE 120 tiller heads were too tightly restricted.
Contact a technician to check if your tiller head requires a software/firmware update specifically designed to resolve "implausible signal" errors. jungheinrich eje 120 error code 4372 top
The most common factory solution for an intermittent error 4372 is a . Jungheinrich released a firmware fix specifically to widen the neutral zone setting so the system is less sensitive to minor sensor wear.

Turn off the ignition completely and disconnect the industrial battery plug. Wait approximately two minutes for the internal controller capacitors to discharge fully. Ensure that the tiller handle is straight up and that no drive butterflies or hydraulic levers are being touched before reconnecting the battery and restarting the truck. 2.

: Tiller head (handle), specifically the drive switch or lift/lower potentiometer.
Follow these steps to diagnose and clear the fault on your Jungheinrich pallet jack. 1. Perform a Hard Reset
: The internal sensors detect conflicting or mathematically impossible voltage values from the tiller controls.
Measure the resistance on the signal supply lines while slowly swinging the tiller handle back and forth. Any sudden jump to infinite resistance indicates a broken internal wire that requires patching or replacement. Step 4: Apply Firmware Updates (Software Calibration)
