Input Devices: Notes

ECU determines control of various output devices based upon signals received from input devices. These devices can include sensors and switches, or simple monitored circuits, such as a RPM reference signal from ignition coil.

Vehicles are equipped with different combinations of input devices. Not all devices are used on all models. To determine input usage on a specific model, see WIRING DIAGRAMS article in the ENGINE PERFORMANCE Section. Available input signals include following:
