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.
Clearance between
lever and stop screw | Between terminals | Resistance
0 mm (0 in.) | VTA–E2 | 0.3–6.3 kΩ
0.41 mm (0.016 in.) | IDL–E2 | 0.5 kΩ or less
0.48 mm (0.019 in.) | IDL–E2 | Infinity
Throttle valve fully
open | VTA–E2 | 2.0–10.8 kΩ
– | VC–E2 | 3.5–6.5 kΩ
