Closed Throttle Position Switch

OPERATION
The idle position switch, which is a contact type switch, senses accelerator operation. The switch is installed at the tip of the ISC servo. When the throttle valve is at idle opening, the ISC lever pushes the push pin to turn on the contact.

TROUBLESHOOTING HINTS
When short-circuit or wire breakage occurs in the idle position switch circuit, the dashpot control is not executed. Therefore, the revolution speed rapidly drops according to the opening degree of the accelerator during deceleration.
