PEDAL POSITION SENSOR (PPS)

OPERATION OVERVIEW

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.

LOCATION

PPS TEST

The PPS can be tested utilizing Digital Wrench® by
verifying that throttle position readout varies as the pedal
is pressed. There should not be any dead spots in the
reading if using the graph mode in Digital Wrench.
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 13% when the pedal is released.
With the pedal fully depressed, the Throttle Position will
vary depending on what gear you have selected.
• High ≈ 60%.
• Low ≈ 39%.
• Neutral / Reverse / Park ≈ 19%
The Pedal Position Sensor is calibrated to the throttle
pedal. If the PPS is faulty, the throttle pedal assembly
must be replaced (see Chapter 4 – PPS Replacement,
page 4.36).

PPS REPLACEMENT

The PPS is calibrated to the throttle pedal. If the PPS is
faulty, the throttle pedal assembly must be replaced.
1. Remove the drivers seat and disconnect the
negative (-) battery cable.
2. Disconnect the PPS harness connection
on the throttle pedal.
