The Jungheinrich EJE 120 relies on a precise analog voltage curve to determine when the control tiller is in its neutral rest position versus when an operator is actively calling for drive, lift, or lower commands. If the electronic control unit (ECU) detects an unexpected voltage profile, it drops into a fault state. The problem generally stems from three specific culprits: 1. Ultra-Narrow Electronic Neutral Zone

to expand the "neutral zone window," making the sensor less sensitive to minor mechanical wear. Teach-In Process

If the fault persists after checking the wiring and restarting: tiller head sensor/card may be faulty and require replacement. In rare cases, the signal-evaluating controller However, the most common culprit for this specific

For more information on Jungheinrich EJE 120 error code 4372 or other technical issues, consult the following resources:

Inspect the steering and tiller components for physical backlash or mechanical wear that could be causing the sensor to provide inconsistent readings.

: Indicates that the signal from the controller's internal potentiometer or magnetic sensor is implausible . The logic board registers a voltage output that is physically impossible under standard operating conditions (e.g., simultaneous signals or voltage out of bounds). Symptoms of Code 4372 on the EJE 120 If the electronic control unit (ECU) detects an

Wait 30 seconds before reconnecting and turning the key back on.

Resolving Error Code 4372 permanently requires one of three distinct actions, ranging from a software update to hardware remediation. Flashing the Tiller Head Firmware

: Jungheinrich is aware of this common error. A known fix is a firmware update for the tiller head that expands the neutral zone "window".
