Investments carry a high level of risk and may not be suitable for all investors.
The "window" for what the truck considers a neutral position is sometimes too narrow. Even a tiny amount of wear or a slight shift in the tiller's resting position can cause the signal to drift outside this window, triggering the "implausible" error.
By following the systematic diagnostic approach outlined above—starting with a battery load test and progressing through high-resistance connection checks—you can resolve code 4372 efficiently and get your pallet truck back to work.
This error is frequently reported when there is no clear neutral zone detected in the tiller head components. While a restart might temporarily clear the fault, it often recurs during operation. jungheinrich eje 120 error code 4372 work
The throttle sensor (potentiometer) within the tiller head may be worn, dirty, or misaligned, sending an incorrect signal to the truck controller. 2. Neutral Zone Issues
If the error persists after a restart, the traction sensor (located in the drawbar/tiller head) may be damaged or out of adjustment. The "window" for what the truck considers a
The internal electronics are the most common point of failure for intermittent errors.
: Often, the most effective solution isn't a wrench, but a laptop. Jungheinrich released a firmware update for the tiller head specifically to expand this "neutral window," making the sensor less sensitive to tiny movements or wear. The Hardware Swap This error is frequently reported when there is
: Ensure technicians use electrical contact cleaner and dry compressed air on the tiller head internals during scheduled preventative maintenance checks.
Loose mounting bolts can cause the sensor to shift away from its reading target, tricking the controller into registering an invalid handle position. Step 5: Battery and Connection Audit
