11.2.2 PWM Sensor Configuration
When mounted on the pedal and lever the target duty cycle should be as
shown in figure 11.2. It is possible however to deviate from these values by
adjusting the throttle configuration within EST.
All PWM sensors used should have a sinking driver with a frequency of 500Hz
(+/- 50Hz). The sensor must give a valid output within 150ms of the main
power being supplied to the sensor.
Position
Acceptable signal
duty cycle range
Released (Low Idle) 10 to 22%
Fully Depressed 75 to 90%

11.2.3 PWM Sensor Installation
There are two PWM throttle inputs available allowing a maximum of two PWM
throttles to be connected directly to the engine ECM. These devices may be
pedal, lever or cable operated. A regulated 8V, 100mA power supply is
provide by the ECM.
