Throttle Valve Visual Check

1. Remove air cleaner outlet hose with ignition mode of keyless push start system in "OFF", see «AIR CLEANER COMPONENTS»(ref-585578-S28303824262013111200000) .
2. Check that there is not any foreign materials caught between throttle valve and throttle body. If there is, take it out after removing throttle body and clean inside of throttle body thoroughly, see «THROTTLE BODY ASSEMBLY REMOVAL AND INSTALLATION»(ref-585578-S00015605662013111200000) .

Scheme 38

1. Remove air cleaner outlet hose with ignition mode of keyless push start system in "OFF", see «AIR CLEANER COMPONENTS»(ref-585578-S28303824262013111200000) .
2. Disconnect connector from electric throttle body assembly.
3. Check throttle valve operation as follows. If faulty condition is found, replace throttle body, see «THROTTLE BODY ASSEMBLY REMOVAL AND INSTALLATION»(ref-585578-S00015605662013111200000) . Check that throttle valve (1) moves smoothly from fully closed position and fully open position with finger. Check that throttle valve returns to default position. Throttle valve default position "a": 7° from completely closed position (1)

Scheme 39

1. Remove air cleaner outlet hose with ignition mode of keyless push start system in "OFF", see «AIR CLEANER COMPONENTS»(ref-585578-S28303824262013111200000) .
2. Push engine switch to change the ignition mode to "ON".
3. Check electric throttle body system as follows. If faulty condition is found, go to step 4). Depress accelerator pedal gradually and check that throttle valve moves smoothly until it opens fully. Release accelerator pedal and check that throttle valve moves back to applicable position. Throttle valve opening angle "a": 3 to 15° from completely closed position (1)
4. Check the following points: If check results are not satisfactory, replace throttle body assembly. Wire harness and connections APP sensor: «APP SENSOR INSPECTION»(ref-585630-S40020050102013111200000) TP sensor: «THROTTLE POSITION (TP) SENSOR PERFORMANCE CHECK»(ref-585630-S32233331482013111200000) Throttle motor: «THROTTLE MOTOR CHECK»(ref-585630-S05544710552013111200000)

Scheme 40

1. Disconnect connector from electric throttle body assembly with ignition mode of keyless push start system in "OFF".
2. Measure resistance between terminals "1" and "2" of throttle body assembly. If faulty condition is found, replace electric throttle body assembly, see «THROTTLE BODY ASSEMBLY REMOVAL AND INSTALLATION»(ref-585578-S00015605662013111200000) . Throttle motor resistance 0.3 - 100 ohms at 20°C (68°F)

Scheme 41

Scheme 42

1. Remove air cleaner outlet hose with ignition mode of keyless push start system in "OFF", see «AIR CLEANER COMPONENTS»(ref-585578-S28303824262013111200000) .
2. Disconnect connector from electric throttle body assembly.
3. Check TP sensor (main and sub) output voltage as follows. If faulty condition is found, replace throttle body, see «THROTTLE BODY ASSEMBLY REMOVAL AND INSTALLATION»(ref-585578-S00015605662013111200000) . Connect 3 new 1.5 V batteries (1) in series and check that total voltage is 4.5 - 5.0 V. Connect voltmeter (2) and batteries to TP sensor as shown in figure. Check that voltage varies depending on throttle opening angle as shown in figure while throttle valve is opened and closed by finger.
