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 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 Location
The pedal position sensor
1
is located on the top of the
accelerator pedal lever.
PPS Test
The PPS can be tested utilizing Digital Wrench by
verifying that the throttle position readout varies as the
pedal is pressed. Reference the Data Display section
and be sure Throttle Position is displayed. Throttle
Position should display as follows:.
• Key on for less than 10 seconds and pedal
released, ≈ 2.8%
• Key on for more than 10 seconds and pedal
released ≈ 10.8%
• Pedal fully depressed ≈ 99.6%
The PPS is calibrated to the throttle pedal. If the PPS is
faulty, the throttle pedal assembly must be replaced.
PPS Replacement
1. Disconnect the PPS harness connection
