HOW TO RESET AUTO IDLE MOTOR?

STEP 1: GATHER YOUR TOOLS

Before starting the process of resetting the auto idle motor (IAC) valve, it's essential to gather the necessary tools. You will need:

• A socket set
• A screwdriver (type may vary depending on your vehicle)
• Carburetor cleaner or throttle body cleaner
• A clean rag
• Safety gloves

These tools will help you efficiently remove, clean, and reinstall the IAC auto idle motor valve, ensuring a smooth operation.

STEP 2: LOCATE THE AUTO IDLE MOTOR

To begin resetting the auto idle motor (IAC) valve, you first need to locate it in your vehicle. The auto idle motor is usually positioned on or near the throttle body, which is part of the intake manifold.

For the precise location and additional details, refer to your vehicle’s manual. This resource provides specific guidance tailored to the make and model of your car, ensuring you find and access the auto idle motor correctly.

STEP 3: DISCONNECT THE BATTERY

Before proceeding with any work on the auto idle motor (IAC) valve, it is crucial to disconnect the battery. Start by removing the negative terminal, which helps prevent electrical issues and unintended sparks during the procedure.

Disconnecting the battery also resets the vehicle's electronic control unit (ECU). This is necessary for the ECU to recognize and adapt to changes made to the IAC valve once reconnected and operational.

STEP 4: REMOVE THE AUTO IDLE MOTOR

First, disconnect the electrical connector on the auto idle motor. Grip the plug firmly and pull it away from the valve, ensuring not to tug on the wires. This step is critical as it isolates the valve electrically, making it safe to proceed with the removal.

Next, use the appropriate screwdriver or socket to remove the screws that secure the auto idle motor to the throttle body. These screws may be tight, so apply consistent pressure to avoid stripping the heads. Keep them safe as you will need them to reattach the valve.

Finally, gently remove the auto idle motor from its position on the throttle body. It should come away easily once the screws are removed. Handle the valve carefully to avoid damaging it, as it is essential for controlling the engine's idle speed.

STEP 5: CLEAN THE IAC VALVE

Start by inspecting the auto idle motor and its seat for any signs of dirt, carbon buildup, or debris. A thorough inspection is crucial to identify all areas that need cleaning. Pay particular attention to the valve tip and the area around the seat, as these are common places for deposits to accumulate.

Proceed to clean the auto idle motor by using a carburetor or throttle body cleaner. Spray the cleaner directly onto the valve and inside the valve cavity. Use a clean rag to scrub away any grime and buildup, ensuring all components are clean and free from obstruction.

After cleaning, it's important to allow the auto idle motor to dry completely. Leaving the valve to air dry ensures that no cleaner residue remains that could interfere with its operation. Ensure the valve is entirely dry before proceeding with reinstallation.

STEP 6: REINSTALL THE AUTO IDLE MOTOR

Carefully position the cleaned auto idle motor back into its housing on the throttle body. Make sure it aligns properly with the mounting points to ensure a snug and correct fit. This alignment is crucial for the proper functioning of the valve once the vehicle is running.

Next, secure the valve by reattaching the mounting screws. Tighten each screw gradually to avoid cross-threading or over-tightening, which can damage the valve housing or the throttle body. Even pressure during this step ensures the valve is mounted securely.

Finally, reconnect the electrical connector to the auto idle motor. Ensure that the connector snaps into place firmly and is not loose, as a poor connection can lead to malfunctions in the valve's operation. This reconnection is vital for the electronic control unit to communicate with the valve correctly.

STEP 7: RECONNECT THE BATTERY AND PERFORM IDLE RELEARN

Reconnect the negative terminal of the battery to restore power to your vehicle. This step is essential for reactivating the vehicle's electrical system and enabling you to perform the necessary engine tests and adjustments. Ensure the terminal is securely fastened to prevent any electrical inconsistencies.

Start the engine and allow it to idle. Initially, the engine might idle unevenly or feel different as the electronic control unit (ECU) recalibrates based on the clean and reinstalled auto idle motor. This recalibration is normal and necessary for the ECU to adjust the engine's idle settings correctly.

Perform the idle relearn procedure by letting the vehicle idle uninterrupted for about 10 minutes. This duration allows the ECU to fully adapt to the clean auto idle motor's operation. If your vehicle has specific relearn procedures, refer to the vehicle's manual to execute them correctly. This step ensures that the engine runs smoothly at idle.

STEP 8: TEST DRIVE

After the idle relearn procedure, it's important to test drive your vehicle to evaluate the effectiveness of the maintenance performed on the auto idle motor (IAC) valve. During the drive, pay close attention to how the engine idles at traffic stops and when the vehicle is in neutral. This helps verify that the idle speed is consistent and smooth.

Observe the vehicle for any signs of irregular idling or stalling that may still be present. A successful reset and cleaning of the auto idle motor should result in a noticeable improvement in engine stability and response. If issues persist, further investigation or professional assistance might be required.

FAQ

1. What is an auto idle motor iac and what is its function in the car?

The idle air control valve (IAC or IACV) also called idle speed control (ISC) or auto idle motor is used on fuel injected engines to control idle speed. The auto idle motor type of IAC features a pintle, which is used to either block or open throttle air passages. The powertrain control module (PCM) controls auto idle motor operation.

2. Which are the symptoms of a broken IAC/Auto Idle Motor?

Not surprisingly, a broken IAC auto idle motor often results in engine idle problems. An engine that is idling too fast or too slow may point to a faulty IAC auto idle motor. An engine that stalls out may indicate IAC auto idle motor problems as well.

3. How can I check, if my IAC/Auto Idle Motor is broken?

Typically, if there is a problem with the IAC auto idle motor or its control circuit, the PCM will set a diagnostic trouble code (DTC) and turn on the check engine light (CEL). If the light is on, you can plug a diagnostic scan tool into the diagnostic port under the dash and read the stored trouble codes. If the codes indicate a problem with the IAC or its circuit, a vehicle specific repair manual should be consulted for further testing.

4. How do I change the IAC/Auto idle motor in my car?

IAC auto idle motor replacement varies from vehicle to vehicle, but it is fairly straightforward in most cases. Vehicle specific repair information should be consulted before replacing your IAC. Typical IAC auto idle motor replacement is as follows:

• Disconnect the negative battery terminal
• Disconnect the IAC auto idle motor electrical connector
• Remove the IAC auto idle motor  attaching screws
• Remove the IAC auto idle motor assembly
• Install in the reserve order of removal
