PEDAL POSITION SENSOR (PPS)

OPERATION OVERVIEW

NOTE
DO NOT attempt to service the PPS. The PPS is a non-
serviceable component and can only be tested using
Digital Wrench®. If the PPS is faulty, the entire throttle
pedal assembly must be replaced.
Mounted to the throttle pedal assembly, the PPS acts as
a pedal position sensor. The PPS provides accelerator
pedal position to the Electronic Control Unit (ECU) to
increase or decrease engine RPM using the Electronic
Throttle Control (ETC). The PPS is the primary input
used to control engine speed during vehicle operation.

PPS TEST

The PPS can be tested utilizing Digital Wrench® by
verifying that pedal position readout varies as the pedal
is pressed. Reference the Data Display section and be
sure the Pedal Position is displayed. With the ignition key
on for at least 15 seconds and engine not running, the
Pedal Position will read approximately 9.6% when the
pedal is released. With the pedal fully depressed, the
Throttle Position will vary depending on what gear you
have selected.
• High/Neutral/Park/Invalid – 100%.
• Low – 100%
• Reverse – 100%
NOTE
If the PPS fails, disconnect the battery power for 10
min. and retest.
The Pedal Position Sensor is calibrated to the
accelerator pedal. If the PPS is faulty, the accelerator
pedal assembly must be
