OPERATION
The closed throttle position switch functions to
l
convert (to HIGH/LOW-level voltage) data as to
whether the accelerator is depressed or re-
leased, and to input that voltage (as signals) to
the engine control module. The engine control
module, based upon those signals, regulates the
idle-speed control motor.
TROUBLESHOOTING HINTS

of the checking of the closed throttle position

Voltage within the engine control module is ap-
l
plied, 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
so the current is grounded.
As a result, the closed throttle position switch
terminal voltage changes from HIGH to LOW
level.
(1) Improper adjustment of the accelerator cable or
the automatic-cruise-control cable.
(2) Improper adjustment of the fixed SAS.
