THROTTLE CONTROL SENSOR (TCS)

THROTTLE LEVER POSITION SENSOR
OVERVIEW
NOTICE
DO NOT attempt to service the Throttle Lever Position
Sensor. The Throttle Lever Position Sensor is a non-
serviceable component and can only be tested using
Digital Wrench®. If the Throttle Lever Position Sensor is
faulty, the entire right hand control assembly must be
replaced.
Mounted to the right hand control assembly, the Throttle
Lever Position Sensor acts as a throttle position sensor.
The TCS provides throttle lever position to the Electronic
Control Unit (ECU) to increase or decrease engine RPM
using the Electronic Throttle Control (ETC). The Throttle
Lever Position Sensor is the primary input used to control
engine speed during vehicle operation.

THROTTLE CONTROL SENSOR TEST

The TCS can be tested utilizing Digital Wrench® by
verifying that throttle position readout varies as the pedal
is pressed. Reference the Data Display section and be
sure Throttle Position is displayed. With the ignition key
on for at least 15 seconds and engine not running, the
Throttle Position will read approximately 9.6% when the
throttle lever is released.
