Idle Speed/Throttle Actuator - Electronic: Testing and Inspection

1. Warm up the engine.
2. Check if a click noise is heard and the engine speed increases to approx. 1,200 rpm when the Idle Speed Control (ISC) solenoid valve connector is disconnected at idle speed.
3. If the engine speed does not change, replace the Idle Speed Control solenoid valve.
4. Check the resistance of the Idle Speed Control solenoid valve.

Resistance: 11 - 13 Ohms (at 68°F [200°C]).

5. If not as specified, replace the unit.
