The continuous pivoting and tilting of the EJE 120 handle stresses the internal wiring harness. Small micro-fractures in the signal wires or loose pins inside the plug connections can interrupt the analog data path to the main controller, mimicking a failed sensor. Step-by-Step Troubleshooting and Diagnostic Process
) can cause the sensor signal to be interpreted as "implausible". Troubleshooting Steps: How to Fix EJE 120 Error 4372
Unscrew the protective shroud covering the interior of the tiller head assembly. Trace the flexible ribbon cables running from the individual sub-switches to the primary terminal board, checking closely for tight pin connections, pinching, or exposed wiring. Proven Technical Solutions jungheinrich eje 120 error code 4372 top
Error code on a Jungheinrich EJE 120 typically indicates that there is no neutral zone detected in either the drive or lift/lower functions. This is a common issue often related to the steering maps and tiller head software. Common Causes & Solutions
, this guide will help you understand the issue and potential fixes The continuous pivoting and tilting of the EJE
Remove the outer plastic housing shells of the tiller head. Visually check for broken plastic structural clips on the spring-return butterfly mechanisms. If the return springs are weak, the drive controls will sag out of true neutral, sending a low voltage that fires off error 4372. Use a specialized electronic contact cleaner to safely displace any hidden water, condensation, or oils. 3. Wire Continuity Check
