OPERATION
The throttle position sensor converts the throttle position opening into a voltage and inputs it to the
l
The 5 V power in the engine control module is supplied to the throttle position sensor. Through
l
the resistor in the sensor, it is grounded in the engine control module.
As the throttle valve shaft rotates from the idle position to wide open position, the resistance between
l
the variable resistor terminal of the throttle position sensor and the ground terminal increases. As
a 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 transaxle 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.
