If the motor draws excessive current due to a shorted winding or a phase-to-ground fault, the motor cannot achieve the commanded torque. The controller commands more current, the motor groans, but speed remains low. The resulting deviation triggers Code 4372. This is more common on older EJE 120 units used in high-duty-cycle applications (e.g., beverage distribution).
: Inspect the tiller head for obvious backlash or loose components that might prevent the sensor from returning to a true neutral position. jungheinrich eje 120 error code 4372
Error Code 4372 is a specific diagnostic message from your forklift's central computer. The error points to a located inside the tiller head. The tiller head is the control hub of the truck, using sensors to translate your physical movements (pushing, pulling, and raising/lowering the tiller arm) into electronic commands for the drive and hydraulic systems. If the motor draws excessive current due to
Remove the tiller head cover casing. Use electronic cleaner spray to remove dust, debris, or moisture buildup around the sensor cards. Step 2: Test the Sensor Voltage Outputs This is more common on older EJE 120

Later-model EJE 120 units include a pressure transducer to monitor hydraulic load. If the sensor reports pressure when the pump is off, or zero pressure when lifting a heavy load, the logic circuit logs code 4372.
