THROTTEL POSITION SENSOR
OPERATION
The throttle position sensor converts the
throttle position opening intovoltage and
inputs it to the engine control unit;,which then
controls the fuel injection based on the input
signal.
The 5 V power in the engine control unit is
supplied to the throttle position sensor
Through the resistor in the sensor; it is earthed
in the engine control unit
As the throttle valve shaft rotates from the idle
position to wide open position, the resistance
between the variable resistor terminal of the
throttle position sensor and the earth terminal
increasesAsa result, the voltage at the
throttle position sensor variable resistance
terminal also increases

TrOUBLESHOOTING HINTS
Hint 1: The throttle position sensor signal is more
important in the control of automatic
transmission than in the engine control_
Shifting shock and other troubles will be
caused if this sensor is faulty:
Hint 2: If the output voltage of the throttle position
sensor is out of specification, adjust the
sensor and check the voltage again: If there
is an evidence of disturbed fixed SAS
setting; adjust the fixed SAS.
