Verify TPS Tester Reference Voltage
A 5 volt reference voltage from the TPS Tester harness is
required for the TPS test to be accurate. Refer to the instructions
provided with the TPS Tester (2201519-A) or follow the bullet
point steps below to check reference voltage.
Reference Voltage Test:
• Insert black voltmeter probe into the test port as shown.
• Insert red voltmeter probe into the test port as shown
and verify the voltage reads 4.99-5.01 Vdc. If the
reading is low, replace the 9 volt battery.
IMPORTANT: Always use a fresh 9 Volt battery.
TPS Replacement
NOTE: The correct position of the TPS angle on the
throttle body is established and set at the factory. If
the TPS is replaced or has been loosened it must be
repositioned to obtain the proper voltage reading.
1. Remove the seats, rear service panel and the rear cargo box
(see Chapter 5).
2. Loosen the hose clamps retaining the throttle body.
3. Remove the throttle body from the intake track and plug the
intake boots with a clean shop towel.
4. Disconnect the vehicle harness from the TPS.
5. Remove the (2) Phillips-head mounting screws and replace
the TPS. Reconnect the vehicle harness to the TPS.
NOTE: If replacing the TPS or throttle body, you
must set the TPS voltage to specification.
IMPORTANT: The TPS voltage reading using the TPS
Tester tool will differ from the reading you get using
the Digital Wrench™ data display. Refer to the
following procedures.
TPS Adjustment Using Digital Wrench™:
1. Assemble SmartLink Module and connect the diagnostic
interface cable to the vehicle to allow Digital Wrench™
use (see “Digital Wrench™ - Diagnostic Connector”).
2. Select the appropriate vehicle and open the data display
grid. Click on the meter icon next to “TPS Volts”.
