Electronic Throttle Assembly

On-vehicle Inspection

1. Check the electronic throttle assembly. 

a. When power is off, the throttle valve plate should be in 

NLP position. If you flip the valve plate by hand, it can 
rotate smoothly. If sticking occurs, which indicates 
internal components may be damaged, replace the 
electronic throttle assembly. 

b. Connect X-431 3G diagnostic tester to Data Link 

Connector (DLC). 

c. Turn ignition switch ON and turn on X-431 3G diagnostic 

tester.

d. Read data flow on X-431 3G diagnostic tester. 

 Release accelerator pedal.

 Depress accelerator pedal. 

If result is not as specified, check wire harness, ECM or 
replace electronic throttle assembly. 

Removal

1. Turn off all the electrical equipment and ignition switch. 
2. Disconnect the negative battery cable.
3. Remove the engine trim cover assembly (

See page 10-10

).

4. Remove the electronic throttle assembly.

CAUTION

 Temperature of hood is very high when engine is running. Before removal, make sure engine has 

stopped running and hood has cooled down, otherwise, there is a risk of scald injury.

 Be sure to wear necessary safety equipment when repairing to prevent accidents.
 Try to prevent body paint surface from being scratched during removal and installation.

CAUTION

 After disconnecting throttle body preheat water inlet hose and outlet hose, cover the hoses with wooden 

corks or equivalent to prevent coolant in hoses from flowing out.

 If your body contacts coolant accidentally, clean it with water immediately. If it is serious, please go to 

hospital.

 DO NOT allow engine coolant enter electronic throttle assembly. If the coolant enters, wipe them with a 

clean cotton yarn immediately. 

ENVIRONMENTAL PROTECTION

 Wasted coolant should be handled by the specialized department according to local laws and 

regulations. Never discard it at will.
