THROTTLE POSITION SENSOR (TPS)
TPS OPERATION OVERVIEW
The pedal position sensor
q
is located on the top of the
accelerator pedal lever. The TPS provides throttle pedal
position to the Electronic Control Unit (ECU) to increase
or decrease engine RPM using the Electronic Throttle
Control (ETC). The TPS is the primary input used to
control engine speed during vehicle operation.
IMPORTANT
DO NOT attempt to service the TPS. The TPS is a non-
serviceable component and can only be tested using
Digital Wrench®. If the TPS is faulty, the entire throttle
pedal assembly must be replaced.
TPS TEST
The TPS 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 TPS is calibrated to the throttle pedal. If the TPS is
faulty, the throttle pedal assembly must be replaced.
TPS REPLACEMENT
1. Remove the drivers seat and disconnect the negative
(-) battery cable.
2. Disconnect the TPS harness connection located on
the throttle pedal.
3. Remove the three fasteners securing the throttle
pedal assembly to the frame support.
4. Remove the pedal assembly from the vehicle.
5. For installation, reverse removal. Torque mounting
fasteners to specification.
