Electric Throttle Body Assembly On-Vehicle
Inspection
S7RS0B1306003
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 accurate 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 thro ttle 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.

NOTE
After replacing electric throttle body
assembly, perform calibration of electric
throttle body assembly referring to “Electric
Throttle Body System Calibration”.

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 Th rottle Body Assembly
Removal and Installation in Section 1D” and clean
inside of throttle body thoroughly.

CAUTION!
• Do not expose APP sensor assembly to
excessive shock like a dropping it. If APP
sensor assembly has been exposed to
excessive shock, it should be replaced.
• Be careful not to expose sensor section of APP sensor assembly to water.

NOTE
After replacing APP sensor assembly,
perform calibration of th rottle valve referring
to “Electric Throttle Body System
Calibration”.
