Idle Speed/Throttle Actuator - Electronic: Testing and Inspection

- Do not pour oil or solvent into the I.S.C. valve.
- Do not disassemble I.S.C. valve.
- Do not peck the valve portion of I.S.C. valve.





1. Check resistance between the terminals.

(A) - (B) : 9.5-10.5 ohms
(B) - (C) : 8.5 - 9.5 ohms

2. Confirm insulation between each terminal and I.S.C. valve body.





3. Apply battery voltage between (B) (+) and (C) (-) and confirm the opening of I.S.C. valve.

Valve: Fully closed.





4. Apply battery voltage between (B) (+) and (A) (-) and confirm the opening of I.S.C. valve.

Valve: Fully open.





5. Check opening clearance of I.S.C. valve without applying voltage to terminals.

Opening clearance: 0 - 2 mm (0 - 0.08 in)





- When installing I.S.C. valve to throttle body, observe the tightening order.

Tightening order: (A) -> (B) -> (C)

Tightening torque: 4 - 5 N.m (0.4 - 0.5 kg-m, 2.9 - 3.6 ft-lb..)
