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 (
).
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.
