Note: Before beginning the throttle position sensor test, adjust the base idle speed.
1. Connect the tester to a standard diagnostic socket.
2. If a tester is not used for testing, then connect a digital voltmeter between the terminal "1 " ("weight") and conclusion "3" (signal) throttle position sensor.
Caution: Do not disconnect the throttle position sensor connector.
3. Turn the ignition key to position "ON" (ON), do not start the engine. Verify that the throttle position sensor signal voltage is within the rated range. If the test is performed using a tester, then read the voltage of the sensor signal (select item #14 of the Hi-Scan tester).
- Rated value: 300-900mV
4. If the measured voltage does not match the rated value, then check that the resistance between "weight" and the output of the sensor signal corresponds to the nominal value.
- Rated value: 3.5-6.5 kOhm
5. If the measured resistance does not match the nominal value, then adjust the throttle position sensor.
6. Adjust throttle position sensor.
- A) Loosen the screws securing the throttle position sensor.
- b) By turning the sensor body, adjust its position so that the output voltage of the sensor corresponds to the nominal value.
Note:
- When the sensor is rotated clockwise, the output voltage of the sensor will increase.
- After replacing the sensor, securely tighten the sensor mounting screws.
7. Turn the ignition key to position "OFF" (OFF).
8. Disconnect the tester or digital voltmeter.
