Be careful not to accurate foreign materials (like dust and metallic particle) to throttle body and throttle valve. Otherwise, throttle body
assembly will break down by throttle valve accretion.
-
Do not apply excessive force to throttle valve for throttle valve operation check and TP sensor performance check. Otherwise, throttle
body assembly will break down by damaging internal resinous gear of throttle valve actuator.
NOTE: After replacing throttle body assembly, calibrate throttle valve position.
