11.CHECKING THE THROTTLE POSITION SENSOR AND IDLE SWITCH CIRCUIT <3000, 3500> <Vehicles builtfromNovember , 1993>
Description of operation
The throttle position sensor and idle switch are
mounted 'in the throttle body and are sensors in
the MPI system
The throttle position sensor converts the opening
position of the throttle valve tovoltage value
and inputs it to the control unit:The control unit
compares this signal with the vehicle speed signal
and changes the amount of actuator control ac-
cordinglyThe idleswitchturnsONandOFF
depending on the voltage value from the throttle
position sensor to compensate for fluctuations or
deviations in the voltage_
