THROTTLE BODY INSPECTION
1. CLEAN THROTTLE BODY BEFORE INSPECTION
(a) Wash and clean the cast parts with a soft brush in
carburetor cleaner.
(b) Using compressed air, clean all the passages and
apertures in the throttle body.
NOTICE: To prevent deterioration, do not clean the thr–
ottle position sensor.
2. CHECK THROTTLE VALVE
Check that there is no clearance between the throttle
stop screw and throttle lever when the throttle valve
is fully closed.
3. CHECK THROTTLE POSITION SENSOR
(See step 2 on page EG1–197)
(c) Gradually turn the sensor clockwise until the ohm–
meter deflects, and secure the sensor with the two
screws.
(d) Using a thickness gauge, recheck the continuity be–
tween terminals IDL and E2.
(b) Insert a thickness gauge (0.70 mm or 0.0276 in.)
between the throttle stop screw and lever, and con–
nect the ohmmeter to terminals IDL and E2.
4. IF NECESSARY, ADJUST THROTTLE POSITION
SENSOR
(a) Loosen the two screws of the sensor.
