FUEL SYSTEM

PEDAL POSITION SENSOR (PPS)

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 throttle position sensor. The PPS provides throttle
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.
