Fast Idle Control Solenoid



The Fast Idle Control (FIC) solenoid is used to supply additional air to the engine in order to maintain the idle speed when the A/C is on.

Removal & Installation

On 1999-00 vehicles, the FIC solenoid is part of the IAC/FIC assembly. Please refer to Idle Air Control Valve, Removal and Installation for the replacement procedure.


  1. With the ignition switch OFF , disconnect the IAC/FIC electrical connector.
  3. Connect the fused jumper wire between the positive battery terminal and terminal 3 of the connector.
  5. Connect one end of the other jumper wire to the negative battery terminal.
  7. Connect the other end of the negative battery terminal jumper wire to terminal 4 of the connector. A click should be heard as the solenoid engages. If not, replace the solenoid.
  9. Unscrew the solenoid from the throttle body. Inspect the plunger and spring for sticking or damage. If either is damaged, replace the IAC/FIC assembly.

Two jumper wires are required for the following tests. An in-line fuse holder with a 30 amp fuse should be spliced in the jumper wire that will be connected to the positive battery terminal to prevent possible damage to the battery, wiring, and components of the circuit being tested.
