Idle Position Switch/Throttle Position Sensor Connector Location:
1. Disconnect Throttle Position Sensor (TPS) connector.
Idle Position Switch Test:
2. Connect an ohmmeter between terminals 1 (sensor ground) and 2 (idle position switch).
Fixed Speed Adjustment Screw (SAS) Adjustment:
3. Insert a 0.65 mm (0.025 in) feeler gauge between the fixed Speed Adjusting Screw (SAS) and the throttle lever.
4. Loosen the TPS mounting bolts and rotate the TPS body fully counter clockwise.
5. The ohmmeter should indicate continuity between terminals 1 and 2.
6. Slowly rotate the TPS body clockwise until the ohmmeter indicates an open circuit between terminals 1 and 2. At this point, tighten the TPS mounting bolts securely.
7. Connect the TPS electrical connector.
8. Connect a digital voltmeter between terminals 1 and 3 of the throttle position sensor connector by carefully backprobing the connector. Do not disconnect the engine control unit connector.
9. Turn the ignition switch ON, but do not START the engine.
10. Measure the TPS output voltage.
Standard Value 400-1,000 mV
11. If the TPS output voltage is outside of the standard values, check the TPS and associated wiring.
12. Remove the feeler gauge.
13. Turn the ignition switch OFF.
