Specified values:

Pedal travel sensor in idle position: 0.6 to 0.85V.
Pedal travel sensor in full throttle position: 110 -130%.

NOTE: If the idle measurement value is outside the above-mentioned limit value, the 71° angle of the lever must be checked and a new lever fitted in the event of correction. Operate accelerator pedal for full throttle position by hand to prevent a distortion of the measured values. Readjust the full throttle stop on the accelerator pedal if the percentage values in the full throttle position do not attain the values mentioned above.
