PEDAL POSITION SENSOR

OPERATION OVERVIEW

NOTICE
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 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
pedal is released. With the pedal fully depressed, the
Throttle Position will vary depending on what gear you
have selected.
• High/Neutral/Park/Invalid – 70%.
• Low – 60%
• Reverse – 32%
The Pedal Position Sensor is calibrated to the throttle
pedal. If the PPS is faulty, the throttle pedal assembly
must be replaced.
NOTICE
If the PPS fails, disconnect the battery for 10 minutes
and retest.

PPS REPLACEMENT

NOTICE
The PPS is calibrated to the throttle pedal. If the PPS is
faulty, the throttle pedal assembly must be replaced.
