EDR Throttle Position Feedback: Notes
The EDR throttle plate position is monitored by two integrated potentiometers. The potentiometers provide DC voltage feedback signals as input to the EMS2000 for throttle and idle control functions.
- Feedback potentiometer 1 provides a signal from 0.5V (LL) - 4.5V (VL),
- Feedback potentiometer 2 simultaneously provides a signal from 4.5V (LL) - 0.5V (VL).
Pot signal 1 is the primary signal, signal 2 is used as a plausibility cross-check through the total range of throttle plate movement.
