Turn the ignition key to the ON position, but do not start the engine.
While holding the throttle valve with your finger in the fully closed position, check the output voltage of the throttle position sensor (1) (channel 1). The required value is 0.4-0.6 V.
If the measured voltage value does not correspond to the required one, loosen the sensor mounting bolts. Rotate the sensor housing until the required sensor output voltage value is achieved.
While holding the throttle valve with your finger in the fully closed position, check the output voltage of the throttle position sensor (channel 2). The required value is 4.2-4.8 V.
If the measured voltage value does not match the specification, replace the throttle position sensor.
With the ignition key in the LOCK (OFF) position, connect the throttle servo connector.
Disconnect the tester.
If a diagnostic trouble code is displayed, clear it with a tester or disconnect the ground cable from the battery for 10 seconds or more.
With the ignition key turned to the ON position, wait 10 seconds, then turn the ignition key to the OFF position. If the battery was disconnected, let the engine idle for 10 minutes.
