INSPECTION
1. CLEAN THROTTLE BODY
(a) Using a soft brush and carburetor cleaner, clean the cast parts.
(b) Using compressed air, clean all the passages and aper- tures.
NOTICE:
To prevent deterioration, do not clean the throttle position
sensor, dashpot and IAC valve.
2. INSPECT THROTTLE VALVE
(a) Apply vacuum to the throttle opener.
(b) Check that there is no clearance between the throttle stop
screw and throttle lever when the throttle valve is fully
closed.
3. INSPECT THROTTLE POSITION SENSOR
(a) Apply vacuum to the throttle opener.
(b) Insert a 0.50 mm (0.020 in.) or 0.75 mm (0.030 in.) feeler
gauge between the throttle stop screw and stop lever.
(c) Using an ohmmeter, measure the resistance between
each terminal.
