Analog input/throttle grip signal implausible.
Note: Disconnect the battery from the engine before working on the connector/throttle grip.
Check the plug for correct contact. Check the plug, cable and throttle grip for damage. Check that the microswitch in the throttle grip clicks near the zero point.
Replace the throttle grip as a test.

Note: The error check is carried out in conjunction with a microswitch in the throttle grip.
If the fault continues to occur, please contact Pendix Service.
