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.
Input Terminal [A]
Output Terminal [B]
Ground Terminal [C]

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.
Remove:
Upper Engine Mounting Bolt [A]
Upper Engine Bracket Bolts [B]
Upper Engine Bracket [C]
Disconnect the throttle sensor connector and connect the
measuring adapter [A] between these connectors.
Main Harness [B]
Throttle Sensor [C]
Special Tool - Measuring Adapter: 57001-1700
Connect a digital meter [D] to the harness adapter leads.
Throttle Sensor Input Voltage
Connections to Adapter:
Digital Meter (+) → R (sensor BL) lead
Digital Meter (–) → BK (sensor BK) lead
