Jungheinrich Eje 120 Error Code 4372 [Ultimate ✭]

On a Jungheinrich EJE 120 , error code 4372 typically signals an implausible signal from the tiller head sensor (specifically related to the analogue values for travel or hydraulic functions).

• Communication Errors: Issues in the CAN bus system or other communication networks within the vehicle.
• Sensor Malfunctions: Faults in sensors related to various systems (e.g., hydraulic, steering).
• Programming or Configuration: Issues related to the vehicle's configuration or software.

4. Troubleshooting & Repair Procedure

⚠️ Safety Warning: Disconnect the battery before inspecting wiring. Wear appropriate PPE. jungheinrich eje 120 error code 4372

Description

Error code 4372 on the Jungheinrich EJE 120 typically indicates a plausibility error in the motor speed feedback circuit. This usually points to an issue with the encoder (resolver/Hall effect sensor) or the wiring between the drive motor and the controller (traction inverter). The truck will likely experience reduced performance, jerky movement, or complete drive cutoff when this error appears. On a Jungheinrich EJE 120 , error code

• Immediate travel cut-off – The truck moves very slowly or not at all.
• Lift function disabled – The forks will not raise, or they raise extremely slowly.
• Intermittent occurrence – The code may appear only during heavy lifting or at the top of the lift stroke.
• Code 4372 stored – The error remains in memory even after cycling the key (active until cleared or fixed).
• No other codes – Sometimes 4372 appears alone, but it can also accompany hydraulic temperature or voltage-related codes.

Operators often report the error appearing randomly during travel in either direction; sometimes a simple temporarily clears the fault. Forkliftaction Immediate Troubleshooting Steps Check Tiller Neutral: Communication Errors: Issues in the CAN bus system

Step 4: Test the Hydraulic Valve Coil

• Locate the hydraulic power unit (under the front cover).
• Disconnect the two wires going to the lift valve coil.
• Set multimeter to resistance (ohms). Measure across the coil’s two terminals. A good coil reads 10–30 ohms (exact value varies; common is approx. 18 ohms).
• Infinite ohms = open coil (replace). 0 ohms = shorted coil (replace). Also check for short to ground: one probe on a coil terminal, the other on a clean ground point – should be infinite.

Firmware Update: 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.

Jungheinrich EJE 120 , Error Code 4372 typically signals an analogue implausible issue with the tiller head sensor. This fault frequently disables hydraulic functions, though the drive might sometimes remain operational. Understanding the Error
