Throttle Full Close Switch: Testing and Inspection
CLOSED THROTTLE POSITION SWITCH
OPERATION
-
The closed throttle position switch functions to convert (to HIGH/LOW-level voltage) data as to whether the accelerator is depressed or
released, and to input that voltage (as signals) to the engine control module. The engine control module, based upon those signals, regulates the
idle air control motor.
-
Voltage within the engine control module is applied, by way of the resistance, to the closed throttle position switch. When the foot is taken off
the accelerator, the closed throttle position switch is switched ON, so the current is grounded. As result, the closed throttle position switch
terminal voltage changes from HIGH to LOW level.
TROUBLESHOOTING HINTS
If there is an abnormal condition of the closed throttle position switch output even though the results of the checking of the closed throttle position
switch harness and of the component itself indicate a normal condition, the cause is probably one of the following.
1. Incorrect adjustment of the accelerator cable or the cruise-control cable.
2. Incorrect adjustment of the fixed Speed Adjustment Screw (SAS).
