Connect the tester to the diagnostic socket.
Turn the ignition key to the ON position (ON), but do not start the engine.
While holding the throttle valve fully closed with your finger, check the output voltage of the throttle position sensor (1) (1st channel). The required value is 0.4-0.6 V.
If the value of the measured voltage does not correspond to the required one, loosen the sensor mounting bolts. By rotating the sensor body, achieve the required value of the sensor output voltage.
While holding the throttle valve fully closed with your finger, check the output voltage of the throttle position sensor (2nd channel). The required value is 4.2-4.8 V.
If the measured voltage is not correct, replace the throttle position sensor.
Turning the ignition key to the LOCK position (OFF) - (OFF), connect the throttle servo connector.
Disconnect the tester.
If a diagnostic trouble code is displayed, clear it with a tester or disconnect the ground wire from the battery for 10 seconds or more.
Turning the ignition key to the ON position (ON), wait 10 seconds then turn the ignition key to the OFF position (OFF). If the battery has been disconnected, let the engine idle for 10 minutes.
