1. INSPECT SUB±THROTTLE ACTUATOR
Using an ohmmeter, measure the resistance between the ter-
minals (ACM to A and A±, BCM to B and B±).
Resistance:
0.82±0.98
at 20°C (68°F)
If the resistance is not as specified, replace the actuator.
2. REMOVE SUB±THROTTLE ACTUATOR
Remove the 4 screws and sub±throttle actuator.

3. INSPECT SUB±THROTTLE VALVE
Check that there is no clearance between the throttle stop
screw and throttle valve gear when the subthrottle valve is ful-
ly closed.
4. INSPECT SUB±THROTTLE POSITION SENSOR
(a) Set the sub±throttle valve to fully closed position.
(b) Insert a 0.41 mm (0.016 in.) or 0.48 mm (0.019 in.) feeler
gauge between the throttle stop screw and throttle valve
gear.
(c) Using an ohmmeter, measure the resistance between
terminals.

5. IF NECESSARY, ADJUST SUB±THROTTLE POSITION
SENSOR
(a) Loosen the 2 set screws of the sensor.
(b) Set the sub±throttle valve to fully closed position.
(c) Insert a 0.45 mm (0.018 in.) feeler gauge, between the
throttle stop screw and throttle valve gear. EG±294

(d) Connect the tester probe of an ohmmeter to the terminals IDL
and E2 of the sensor.
(e) Gradually turn the sensor clockwise until the ohmmeter
deflects, and secure it with the 2 set screws.
(f) Recheck the continuity between terminals IDL and E2.
