THROTTLE BODY ASSEMBLY

REMOVAL AND INSTALLATION

M1131007700652

CAUTION

Do not loosen the fixing screws for the resin cover of throttle body assembly. If the screws are loos-
ened, the sensor incorporated in the resin cover becomes misaligned and the throttle body can not 
work normally.

Pre-removal Operation
