With Manual Transaxle

Throttle Switch:

PURPOSE
Provides the Powertrain Control Module (PCM) with a throttle fully closed or throttle fully open signal by means of separate contacts within the sensor.

CONSTRUCTION
Consists of 2 switches sensing only closed or wide open throttle positions. These are referred to as the Idle (IDL) switch and Wide Open Throttle (WOT) switch.

OPERATION
The sensor is rotated by and in conjunction with the throttle shaft so that sensor and shaft positions correspond when the sensor is properly adjusted. At intermediate throttle positions (between fully closed and fully opened), neither sensor contact provides the PCM with a signal. The TP switch inputs to the PCM an idle condition signal to cut off fuel flow during deceleration and control engine idle speed. Wide open throttle input is used to modify fuel flow for maximum engine power output. The PCM uses this information to modify air/fuel mixture, idle speed, injector timing, ignition timing, fuel pressure and purge flow.
