7. If voltage varies with throttle movement, continue on to the
next step. If the sensor did not function correctly, replace it.
8. Allow the throttle lever to rest in the idle position. The
voltmeter should read .700 ± .050 volts.
9. If the voltage does not read within the specification,
proceed to the “TPS Adjustment” procedure. If the
voltage reading is within specification, no adjustment is
required.
TPS Adjustment
NOTE: This procedure should be performed after
you have checked the TPS reading. Refer to
“Checking TPS Reading” procedure before making
any adjustments.
1. Loosen the hose clamp retaining the intake boot to the
intake plenum.
2. Remove the (4) bolts retaining the intake plenum and
throttle body.
3. Position the throttle body to access the TPS screws.
4. Make sure the TPS Tester harness is still connected to the
TPS harness.
5. Loosen the TPS mounting screws.
6. Rotate the TPS until your voltmeter reads .700 ± .050 volts
(see Figure 3-20).
7. Retighten TPS mounting screws and torque to
specification.
8. Verify voltage reading did not change. If voltage reading
changed, repeat steps 5 - 7.
9. Reconnect the vehicle harness to the TPS.
10. Reinstall the throttle body and intake plenum. Torque bolts
to specification.
11. Install intake boot to intake plenum and securely tighten the
hose clamp.
12. Reinstall the left-hand side panel and seat.
13. Start engine and test operation.
