I need to provide comprehensive information, including error meaning, causes, diagnostic steps, and solutions. I should search for relevant information. search results show some relevant sources. The Forkliftaction forums have two relevant threads: one from 2022 and another from 2020. There's also a blog post from Machineseeker and a troubleshooting guide from blog.usro.net. I should open these to gather detailed information. forum discussions provide details about error 4372, describing it as a tiller head failure due to a narrow neutral zone, with firmware updates as a solution. The Machineseeker blog and the troubleshooting guide offer general advice on handling error codes. I have enough information to write a comprehensive article. I will structure the article with an introduction, an explanation of the error, immediate safety steps, detailed troubleshooting procedures, information about related codes, and concluding recommendations. code 4372 on a Jungheinrich EJE 120 is a specific warning about the electronic system in the tiller head—the handle you steer. In simple terms, it means the truck's computer is confused by the readings it's getting from the tiller's neutral zone (the centered position). This is a very well-documented issue with a known solution, and this article will walk you through what it means and how to fix it.
To resolve this issue, consider the following technical steps derived from service discussions: Firmware Update

She then runs the lift command while listening: The pump motor runs briefly but stops after 1.5 seconds – that’s the timeout. The height sensor (a Hall effect sensor inside the mast) is sending “0 mm” signal.
Under the plastic cover at the lower mast, Marta finds the 3-pin connector (power, ground, signal). One pin is corroded – green oxidation. She cleans it with contact spray and reconnects. Restart – same error. user wants a long article about the Jungheinrich
The fault stems from a failure in communication between the tiller's mechanical controls and the main electronic inverter. Technicians usually isolate the issue down to three primary areas: 1. Narrow or Missing Tiller Head "Neutral Zone"
This is a . The system shuts down the lift function to prevent deep discharge of the battery or thermal damage to the lift motor and contactors. search results show some relevant sources
If the contactor that sends power to the hydraulic pump motor is stuck closed (welded) or open (coil failure), the controller sees unexpected voltage on the feedback line, triggering code 4372.
Jungheinrich EJE 120 , error code identifies an analogue tiller head sensor issue where the signal is deemed "implausible"
that expands the "neutral zone" window, making the sensor less sensitive to minor signal fluctuations. Check Tiller Head Sensor
