Idle Stop Solenoid Check

NOTE: A non-functioning idle stop solenoid (if equipped) could cause stalling or rough idle when the air conditioning (if equipped) is turned on.

1. Turn the ignition on but do not start the engine. Turn the air conditioning switch on.
2. Open the throttle momentarily to allow the solenoid plunger to extend.
3. Disconnect the wire at the solenoid. The plunger should pull back from the throttle lever.
4. Connect the solenoid wire. The plunger should move out and contact the throttle lever.
5. If the plunger does not move in and out, check for voltage across the feed wire.
a. If the voltage is 12 to 15 volts, replace the solenoid.
b. If the voltage is low, locate the cause of the open circuit in the solenoid feed wire.
