How can I test my idle control valve?

How can I test my idle control valve?

Open the hood and remove the screws holding the idle control valve to the throttle body on the back of the engine.

  • Unplug the electrical plug running to the control valve.
  • Pull the idle control valve off the throttle body and turn it over to expose the valve openings.
  • Turn the dial on the voltmeter to “Ohms.”

    What does the idle air control motor do?

    An idle air control valve, also called an idle air sensor control motor, is an electrically operated valve that controls the amount of air that bypasses the throttle plate in cars with a fuel injection system [source: Autozone ]. This causes the idling speed of the engine to change as needed.

    Where is idle air control motor?

    The Idle Air Control ( IAC ) motor is mounted on the back of the throttle body. The valve controls the idle speed of the engine by controlling the amount of air flowing through the air control passage.

    What is an air control valve?

    Air control valves are fundamental components of any pneumatic system. Selecting the right air control valves to regulate system pressure, direction of flow, and rate of flow is crucial when designing fluid power circuitry.

    What are the symptoms of a bad IAC valve?

    The IAC controls the rpm in your car by open or closing its valve, and it is controlled by the computer. The IAC valve over time gets dirty and will cause your car to run poorly. Possible symptoms of a bad IAC is irregular rpms, car stalling, and it will cause you to waste more gas than necessary.

    Where is the idle air control motor located?

    The Idle Air Control ( IAC ) motor attaches to the bottom of the throttle body on the 3.3L engine. On the 3.5L engine, the motor is located at the rear of the intake manifold plenum next to the of the left throttle body.

    What is an IAC or idle air control solenoid?

    The Idle Air Control (IAC) solenoid allows the Computer (PCM) to accurately control engine idle under a variety of conditions. The IAC solenoid is driven by an output signal from the PCM and allows intake airflow to bypass the throttle plates. In addition to normal idle speed control the IAC solenoid also functions as a deceleration dashpot and allows for idle changes during periods of increased engine load (A/C, electrical).
