Fault description

Diagnosis monitors whether the throttle valve reaches the lower mechanical limit position during repeated adaptation.

Fault monitoring conditions:

The fault is recognized when the specified limit values for the permissible signal voltages are not achieved during initial adaptation. (Signal voltage sensor 1 less than 0.27 V, signal voltage sensor 2 greater than 4.73 V) or if the total of the signal voltages for sensors 1 and 2 deviates from 5 V by more than 0.6 V.
