or the tiller arm sensor unit itself may need replacement. For further technical assistance, you can consult the official Jungheinrich Service Portal with your vehicle's serial and order numbers.

The system continuously monitors the voltage output from the tiller arm's internal potentiometers and magnetic sensors. When the truck is turned on, or during active travel, the controller checks for a . If the voltage feedback falls outside the preprogrammed safety thresholds (for example, if the accelerator or lift buttons register as simultaneously activated and at rest), the signal is flagged as implausible . To prevent accidental, uncommanded machine movements, the controller locks out the hydraulic circuitry. Primary Causes of the Fault
Imagine it’s the middle of a double shift. Your EJE 120, a reliable workhorse, suddenly "hiccups." You stop to check a manifest, but when you go to move again, the hydraulics cut out or the travel stops entirely. A quick restart might temporarily clear it, but as the day goes on, the error becomes a constant shadow. This is the classic
Check for available factory firmware updates specifically targeting the tiller head parameters. jungheinrich eje 120 error code 4372 work
Many novice technicians see a code 4372 and assume the lift controller is faulty. This is almost never the case. The controller is protecting itself from a real power issue.
Turn the key switch (or enter the PIN code) to shut the truck off completely.
Older software parameters on early-generation EJE 120 units featured an exceptionally narrow tolerance window for the neutral voltage reading. Minor wear instantly threw code 4372 despite the component being fully functional. Step-by-Step Diagnostic and Repair Workflow or the tiller arm sensor unit itself may need replacement
Technicians and community experts from forums like Forklift Action suggest the following steps:
. This typically occurs when the truck's control system cannot detect a clear "neutral" or zero-travel position for the drive or lift/lower functions. Meaning of Error 4372
: Over time, the internal components that translate your hand movements into lifting or driving actions begin to output erratic or incorrect voltages. Discussion: Error 4372 - Forums - Forklift Action
Perform a physical check of the tiller head for any obvious signs of damage, play, or looseness that could affect sensor alignment. If physical damage is found, repair or replace the affected components before proceeding.
