Using A Digital Multimeter (DMM)

1. Remove the air cleaner (if necessary).
2. Insert a 3.5 mm (0.14 in.) feeler gage (2) between the throttle stop screw (1) and the throttle lever (3).




3. Inspect the Idle Speed Control (ISC) motor plunger. If the ISC motor plunger (1) is contacting the throttle lever screw (3), then the engine must be brought to operating temperature. There must be no contact (2) between the ISC motor plunger and the throttle lever screw.
4. Back probe the Throttle Position (TP) sensor signal circuit at the powertrain control module electrical connector to ground.
5. Turn ON the ignition.
6. Observe the TP sensor voltage on the DMM. The TP sensor voltage reading should be 0.98 to 1.02 volts.




7. If the TP sensor voltage IS NOT 0.98 to 1.02 volts, loosen the IP sensor screws (1) and turn the TP sensor until the voltage reading is 0.98 to 1.02 volts.

NOTE: Refer to Fastener Notice in Service Precautions.

8. Tighten the TP sensor screws (1).

Tighten
Tighten the TP sensor screws to 2.0 N.m (18 lb in).

9. If a TP sensor voltage reading of 0.98 to 1.02 volts cannot be obtained, replace the TP sensor.
10. Install the air cleaner.
