Circuit Operation
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
The throttle position sensor signal and idle position signal are sent to the auto-cruise control-ECU through this circuit.
The throttle position sensor sends a voltage signal to terminal 1 of the auto-cruise control-ECU. The voltage depends on throttle opening angle. The auto-cruise control-ECU receives an idle position signal from the ECM < M/T > or PCM < A/T > at terminal 2. The signal is OFF when the accelerator pedal is depressed, and ON when the accelerator pedal is released.
