Idle Switch: Description and Operation
The idle switch signals the ECU when the throttle is closed, indicating a deceleration or idle condition (the ECU decides which condition is present by
comparing the idle switch indication with the engine speed). This is a normally open spring loaded switch. The throttle lever closes the switch when in
the idle position.
