Error code on a Jungheinrich EJE 120 (and related ERE models) typically indicates a Tillerhead Failure . This error usually points to an issue with the traction sensor or the neutral zone calibration in the tiller head. Core Issue: Implausible Tiller Head Sensor
| Cause | Solution | | :--- | :--- | | Faulty lift rocker switch | Replace the complete tiller handle switch assembly (Part # often starts with 511...). | | Damaged wiring harness | Repair chafed wires using heat-shrink butt connectors or replace the tiller cable harness. | | Welded or open contactor | Replace the hydraulic contactor (ensure coil voltage matches truck’s system, usually 24V or 48V). | | Failed ESC | Replace or send for professional repair.

If you'd like to narrow down the problem further, let me know:
: Continuous pivoting of the tiller arm strains the internal wiring harness, resulting in high resistance, intermittent connections, or frayed wires. Step-by-Step Troubleshooting and Repair Workflow Moisture Removal Error code on a Jungheinrich EJE
The error is often triggered because the "neutral zone" (the zero travel position) is too narrow or the analogue signal from the tiller head sensor is deemed "implausible" by the controller. This can cause the truck to cut out hydraulic functions.
: A faulty card or sensor inside the tiller unit can send inconsistent analogue signals, triggering the "implausible" status.
💡 Before calling service, try a full power cycle (off/on) with the tiller perfectly vertical and no buttons pressed. If you'd like, I can help you: Discussion: Error 4372 - Forums - Forklift Action
