Throttle Sensor (Service Code 11)
The throttle sensor is a rotating variable resistor that
change output voltage according to throttle operating.
The ECU senses this voltage change and determines fuel
injection quantity, and ignition timing according to engine
rpm, and throttle opening.

Throttle Sensor Removal/Adjustment
Do not remove or adjust the throttle sensor [A]
since it has been adjusted and set with precision
at the factory.
Never drop the throttle body assy, especially on a
hard surface. Such a shock to the throttle sensor
can damage it.
Throttle Sensor Input Voltage Inspection
Be sure the battery is fully charged.
