"Turn the key to 'On', but don't start the hydraulics," Ray shouted.

While many 1901 faults are resolved by removing debris or repositioning the operator's foot, persistent codes require professional intervention. You should contact your local Jungheinrich service center or certified forklift technician if: Jungheinrich Error Code 1901

Inspect the pedal area for any objects (like small stones or plastic wrap) that might be jamming the mechanism.

What is the of your Jungheinrich forklift (e.g., ERE, EFG, EJC)?

Jungheinrich Error Code 1901 is a specific fault code that appears on the onboard computer or display screen of certain Jungheinrich models.

is a specific, actionable fault indicating a CAN Bus timeout with the drive controller.

By methodically checking power supply, CAN bus resistance, and connector integrity, 70% of occurrences can be resolved without replacing expensive components.

The accelerator pedal position is measured by a sensor, typically a Hall effect sensor (non-contact, using magnetic fields) or a potentiometer. Over time, dirt, moisture, or grime can block the pedal mechanism, preventing it from fully returning to its neutral "zero" position. This results in a constant signal being sent to the controller, triggering the error upon startup.
