Electric Throttle Body Assembly On-Vehicle
Inspection
S6RW0C1306004
WARNING
!
Never touch throttle valve with finger while
ignition switch is turned ON and accelerator
pedal is depressed. Otherwise, injury may
result by pinching the finger between throttle
valve and throttle body housing.
CAUTION
!
• Do not disassemble electric throttle body
assembly.
• Do not expose electric throttle body
assembly to excessive shock like a
dropping it. If electric throttle body
assembly has been exposed to excessive
shock, it should be replaced.
• Be careful not to accrete a foreign material
(like dust and/or metallic particle) to the
throttle body housing and/or throttle valve.
Otherwise, the throttle body assembly is
breaking down by throttle valve accretion.
• Do not apply excessive moving force to
throttle valve for throttle valve operation
check and/or TP sensor performance
check.
Otherwise, the throttle body assembly is
breaking down by damaging the internal
resinous gear of throttle valve actuator.
Throttle Valve Visual Check
1) Remove air cleaner outlet hose.
2) Check that there isn’t any foreign matter caught
between throttle valve and throttle body housing. If
there is, take it out after removing throttle body
referring to “Electric Throttle Body Assembly
Removal and Installation in Section 1D” and clean
inside of throttle body thoroughly.
Throttle Valve Operation Check
1) Remove air cleaner outlet hose.
2) Turn OFF ignition switch.
3) Move throttle valve with finger to its full open position
and check that it moves smoothly.
4) Move throttle valve with finger to its completely
closed position and check that it moves smoothly.
5) Take off finger from throttle valve (1) which is at full
open position and check that it moves smoothly by
its return spring and open spring force back to
default position (position where throttle valve is open
by 7
°
(2) from completely closed position).
6) Take off finger from throttle valve (1) which is at
completely closed position and check that it moves
smoothly by its return spring and open spring force
back to default position.
If check result is not satisfactory, replace electric
