Inhibitor Switch: Description and Operation
Inhibitor Switch Operation
Inhibitor Switch Location
On models with automatic transaxles, the inhibitor switch closes when the transaxle is in Neutral or Park. Based on the state of the inhibitor switch,
the Electronic Control Unit (ECU) senses automatic transaxle load and actuates the Idle Speed Control (ISC) servo to maintain optimum idle speed.
