Jungheinrich Eje 120 Error Code 4372 Top !full! -

Encountering the Jungheinrich EJE 120 error code 4372 "TOP" can be frustrating, but it is a well-understood and documented issue. The good news is that Jungheinrich recognizes the problem and has clear solutions available.

To resolve the Jungheinrich EJE 120 error code 4372 on the top model, follow these troubleshooting steps:

I’m currently working on a Jungheinrich EJE 120 electric pallet jack that is throwing up .

Call maintenance. This is not a user-resettable code without tools. jungheinrich eje 120 error code 4372 top

: The "neutral zone" (the dead zone where no action occurs) is too narrow for the sensor to reliably detect a neutral state.

: Tiller head (handle), specifically the drive switch or lift/lower potentiometer.

A: Yes. The error indicates the truck cannot verify the tiller's neutral position. The safety logic will likely cut drive and lift functions. Do not attempt to override it. Encountering the Jungheinrich EJE 120 error code 4372

Jungheinrich released an official engineering bulletin to address early iterations of this code.

| Cause Category | Specific Fault | Probability | |----------------|----------------|--------------| | | Sticking or jammed limit switch roller (S4) | High | | Electrical | Short to ground or open circuit in S4 wiring | Medium | | Alignment | Cam/bracket misalignment due to mast wear or impact | Medium | | Controller | Faulty input on main board (MOSFET or pull-up resistor) | Low | | Hydraulic | Over-lift due to leaking cartridge valve (allows piston past cutoff) | Rare |

Periodically check the tiller pivot bolts to ensure excessive mechanical play is not throwing off sensor alignment. Call maintenance

Although less common than software issues, physical wear can trigger the error. If there is excessive "backlash on the hairpin" or mechanical play in the tiller linkage, the sensors might drift out of their calibrated range.

After physical repair:

Switch the EJE 120 off and back on. If the error is transient, this may temporarily solve the issue to finish a task.
