ELECTRONIC FUEL INJECTION
TPS Initialization
NOTE: The correct TPS position is established and
set at the factory. Use this procedure only if the TPS
was repositioned, replaced or loosened.
STEP 1
Establishing zero offset voltage: This step is crucial as it sets
the TPS position using a fixed physical stop. This will insure
that the correct offset voltage is reached once the correct throttle
body flow is set.
NOTE: Before proceeding, it’s extremely important
to verify the throttle body bore is clean of any carbon
build-up. Remove the intake boot and inspect the
throttle body bore. If required, remove the throttle
body and clean the bore.
1. Stop the engine and leave the ignition key in the off
position.
2. Remove the driver and passenger seats along with the rear
service panel.
3. Remove the outlet duct from the PVT cover to access the
throttle body.
4. Loosen the hose clamps that secure the throttle body in the
intake boot and intake adaptor. This will allow you to rotate
the throttle body to access the TPS or allow you to remove
the throttle body to perform this procedure.
5. Remove the throttle body side cover and disconnect throttle
cable from throttle cam.
6. Back out air flow screw until it no longer is in contact with
throttle plate cam. The throttle plate should seal off throttle
bore completely.
7. Open and close throttle plate a couple of times to ensure full
throttle closing. Do not snap closed, as this could cause
unnecessary throttle plate to throttle body interference and/
or damage.
8. Assemble the TPS Tester Harness (PU-47082) according to
the instructions. Refer to “TPS Test Procedure” for proper
tester set-up. Verify that the 9 volt battery is new.
9. Disconnect the vehicle harness from the TPS.
10. Plug the TPS tester harness in the TPS harness.
11. Using a voltmeter check the voltage output of the TPS. It
should read .528 ± .01 volts.
