: Check for physical obstructions in the tiller handle that might prevent the controls from returning fully to the neutral position.
Understanding Jungheinrich EJE 120 Error Code 4372 Error code on a Jungheinrich EJE 120 electric pallet jack typically indicates a "tiller head sensor analogue implausible" event. This critical fault generally occurs when the truck’s controller detects that the signals for drive, lift, or lower functions are not in their required "neutral" or "zero" positions during startup or operation.
: Switch the truck off and then back on again. In some cases, this clears minor signal glitches and allows the system to recalibrate its zero-point. jungheinrich eje 120 error code 4372
: If calibration fails, you may need to replace the entire tiller head assembly or the specific faulty analog sensor. Professional Assistance
: Since this is a known issue for many Jungheinrich EJE 120 models, the most effective long-term fix is often a software update using the Jungheinrich Judit diagnostic tool. This update expands the neutral zone, making the truck less sensitive to minor sensor deviations. : Check for physical obstructions in the tiller
: The analog signal from the traction or hydraulic sensor in the drawbar head may be abnormal or "implausible" to the main controller.
Because resolving this code often requires specialized diagnostic software like , it is recommended to contact an authorized Jungheinrich Service Center if basic restarts and wiring checks do not clear the fault.

: If the sensors are functioning but out of alignment, a "Teach-In" process using factory software may be required to redefine the travel and hydraulic limits.
