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
sh
own.
• Insert red voltmeter probe into the test port as
sh
own 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
ca
rgo 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
mu
st set the TPS voltage to specification.
IMPORTANT: The TPS voltage reading using the TPS
Tes
ter 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
diag
nostic 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. Clic
k on the meter icon next to “TPS
Volts”.
