Throttle Position Sensor: Testing and Inspection
Closed Throttle Position (CTP) Switch1. Verify that the throttle valve is at the CTP.
2. Disconnect the TP sensor connector.
3. Inspect continuity between TP sensor connector terminals C and D using an ohmmeter.
- If there is no continuity, adjust the TP sensor.
4. 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.
- If there is continuity, adjust the TP sensor.
Throttle Position (TP) Sensor
1. Connect the SSTs to the DLC2.
2. Verify that the throttle valve is at the CTP
3. Turn the ignition switch to ON.
4. Select the PID/DATA MONITOR AND RECORD function of the NGS.
5. Select "TP V" on the NGS display. NGS measures and shows the voltage.
- If not as specified, adjust the TP sensor.
Specification
- Closed throttle position: 0.1 - 1.1 V
- Wide open throttle: 2.8 - 4.5 V
(Verify that the voltage increase is directly proportioned to the throttle valve opening angle.)
