First Design OnOff Type Sensor

The first design sensor is used on Conventional EFI engines. It utilizes a dual position contact which switches a battery voltage signal to either the IDL or PSW inputs at the ECU. This switching action causes the voltage signal at the ECU to go high whenever the switch contacts are closed.

Referring to the voltage graph, IDL signal voltage is high when the throttle is closed and goes low when the throttle exceeds a 1.5' opening. PSW voltage is low until the throttle exceeds about a 70' opening; then it goes high.
