1. Connect the MUT-II to the diagnostic socket.
2. Disconnect the connector from the throttle position sensor (pic. 6.4).

3. Turn on the ignition, but do not start the engine.
4. Check the Throttle Position Sensor Output Voltage (1st channel), when the throttle is fully closed with your finger.
Sensor output voltage: 0.4-0.6V
5. If the measured value does not correspond to the nominal voltage value, loosen the sensor mounting bolts and adjust its position by turning it to one side or the other (pic. 6.5). Tighten the screws after adjustment.

6. Check the Throttle Position Sensor Output Voltage (2nd channel), when the throttle is fully closed with your finger.
Sensor output voltage: 4.2-4.8V
7. If the measured value does not match the nominal voltage value, replace the throttle position sensor.
8. Turn off the ignition.
9. Connect the connector to the throttle position sensor.
10. Disconnect the MUT-II device from a diagnostic socket.
11. Use the MUT-II to clear diagnostic trouble codes or disconnect the cable from the negative battery terminal for 10 seconds, then reconnect it to the negative battery terminal.
12. Turn on the ignition, wait 10 minutes and turn off the ignition. Also, if you disconnected the negative battery cable in step 11, start the engine and let it idle for 10 minutes.
