The following changes have been made to the document:
Sec. 4: Sensors integrated into the pedal unit may not require an additional return force mechanism.
Sec. 6: Specified each signal channel for Dual APS throttle pedal sensors.
Sec. 6.9: Hysteresis requirement should be a valid statement over the entire span.
Sec. 6.10 and 6.11: Specify that the open or short circuit response is valid at any position.
Sec. 7.2: Changed to 40 mA DC maximum from 100 V DC maximum.
Sec. 7.6: Added reference to Figure 2 for output linearity.
Sec. 7.8: Corrected grammar.
Sec. 7.10: Hysteresis requirement should be a valid statement over the entire span.
Sec. 7.11 and 7.12: Specify that the open or short circuit response is valid at any position.
