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.
When this error triggers, it often results in an immediate cutout of hydraulic or traction functions to ensure safety. Common Causes of Error 4372 jungheinrich eje 120 error code 4372
: 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.
: Damaged, frayed, or loose wiring between the tiller head and the main controller can cause signal fluctuations. Troubleshooting and Resolution Steps To resolve error 4372, follow these diagnostic steps: : If calibration fails, you may need to
: The analog signal from the traction or hydraulic sensor in the drawbar head may be abnormal or "implausible" to the main controller.
: Older EJE 120 models often have steering maps with narrow neutral tolerances. Jungheinrich has released firmware updates specifically to widen this neutral "window" and resolve persistent 4372 errors. When this error triggers, it often results in
The most frequent reasons for this error code appearing on your display include:
: The sensors in the tiller head may not be returning to a true neutral position. If the "window" for what the software considers neutral is too narrow, even a minor physical misalignment can trigger the code.
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. Discussion: Error 4372 - Forums - Forklift Action
