With SST-New Generation Star Tester
INSPECTION(Integral) Closed Throttle Position Switch
1. Verify that the throttle valve is closed throttle position.
2. Disconnect the throttle position sensor connection
3. Check for continuity between throttle position sensor connector terminals C and D by using an ohmmeter.
4. If no continuity, check adjustment of throttle position sensor.
5. Insert a 0.50 mm (0.020 in) feeler gauge between the throttle adjusting screw (TAS) and the throttle lever. Verify that there is no continuity.
6. If there is continuity, adjust the throttle position sensor.
Throttle Position Sensor
With SST-New Generation Star (NGS) Tester
1. Connect the SST to the data link connector-2.
2. Verify that the throttle valve is closed throttle position.
3. Turn the ignition switch to ON.
4. Select the PID/DATA MONITOR AND RECORD function of the NGS.
5. Select "TPS" on the NGS display. NGS measures and shows the voltage.
Specification
Closed throttle position: -0.1-1.1 V
Wide open throttle: 2.8-4.5 V
NOTE: Verify that the voltage increase is directly proportioned to the throttle valve opening angle.
6. If not as specified, adjust the throttle position sensor.
