Jungheinrich recommends checking the tiller head for available software updates. A firmware update often resolves the issue by expanding the acceptable neutral zone range, making the sensor less prone to triggering an "implausible" error.
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. jungheinrich eje 120 error code 4372 work

The neutral zone in the tiller's steering map or hydraulic controls is too narrow. Replace it
: He inspected the steering tiller and lift buttons to ensure they weren't physically stuck or obstructed.
: In some cases, the error is temporary and will clear after a restart, though it will likely recur if the underlying sensor or software issue is not addressed.
