: The "window" for the neutral position in the tiller head is too small, causing the sensor to send an "analogue implausible" signal even if the tiller is at rest. Outdated Firmware
The lift valve is opened by an electromagnetic coil. If the coil’s resistance is out of specification (typically 10–30 ohms, but check your model year), or if it is shorted to ground, the controller detects a current plausibility error and triggers code 4372.
If these basic steps don't clear the code, you may need a technician with the Jungheinrich JUDIT diagnostic tool to adjust the steering map parameters or update the software .
is less common than basic battery or motor faults, but it points to a specific and critical area of the truck’s safety and control system. jungheinrich eje 120 error code 4372
Jungheinrich safety logic will disable drive power. The parking brake will either remain locked (if it failed to release) or, more dangerously, fail to engage. Never bypass or reset this code without a proper repair — an uncontrolled runaway pallet truck is a severe workplace hazard.
Remove the plastic protective shrouds covering the tiller handle base and arm joints.
: Early production years and old-stock parts shipped with a highly sensitive "neutral window" software threshold. Minor mechanical wear can cause the resting voltage to drift outside this narrow parameter. : The "window" for the neutral position in
: As sensors age, accumulate dust, or undergo temperature shifts, their baseline voltage drifts slightly. If the controller registers that the drive or lift switches are resting even a fraction of a millimeter outside the absolute, tight neutral center, it flags Error E4372 and shuts down operations.

If these steps do not clear the code, you may need to replace the tiller head sensor or the internal control card. For further diagnostic support, you can consult professional communities like the Forklift Action Forum . Discussion: Error 4372 - Forums - Forklift Action
“You knew. You did nothing.”
Error code on a Jungheinrich EJE 120 typically indicates a Neutral Zone Error
If you encounter this code, follow these steps to diagnose and potentially resolve the issue:
From that night on, no Jungheinrich in that warehouse ever saw 4372 again. But the older drivers sometimes swore that if you pressed the horn just right at a full stop, the display would blink once, fast: “Forgiven.” If these basic steps don't clear the code,
Check the butterfly travel switches (throttle pads) on both sides of the handle. Do they snap back instantly to the center position when released?
