CAR IDLE AIR CONTROL MOTOR VALVE SYMPTOMS

A malfunctioning or failing IAC car idle motor can lead to various noticeable symptoms in a vehicle. If you experience the issues, such as high or low idle speed, it is a sign of a bad car idle motor. Here are the ways to check idle air control valve functioning:

FLUCTUATING IDLE SPEED 

An unstable or erratic idle speed is the most common symptom of a faulty IAC car idle motor. The engine may rev up and down unexpectedly at a stop or struggle to maintain a consistent idle speed. If the vehicle’s engine is idling at a speed of more than 1,000 RPMs, it’s probably too high. Also, remember that vacuum leaks can cause a higher idle speed. 

Use an onboard diagnostic (OBD) scanner. If it shows a P0507 code, it can be due to the high RPM generated by the idle air control valve.

STALLING

Besides high idle speed, a failing IAC car idle motor is a cause of the engine stalling when idle, especially when coming to a stop or during deceleration. The inadequate control of the idle air can lead to a lean air-fuel mixture, causing the engine to shut off.

ROUGH IDLING

The engine may exhibit rough or lumpy idling, with noticeable vibrations and a lack of smoothness. It may feel like the engine struggles to maintain a consistent idle speed. That said, it can be one of the reasons why the car vibrates when idle.

DIFFICULTY STARTING

A malfunctioning idle speed control valve can cause a car to take longer while starting the engine, especially when the vehicle is cold. This symptom is more apparent during cold weather conditions. It may also be a reason why a car shakes when starting then dies. 

POOR FUEL EFFICIENCY

If the IAC car idle motor is not functioning correctly, it may allow too much or too little air into the engine, affecting the air-fuel ratio. This rough car engine idling can result in reduced fuel efficiency and increased fuel consumption.

CHECK ENGINE LIGHT

A malfunctioning IAC car idle motor can trigger the vehicle’s onboard diagnostics system and become the reason behind the check engine light turning on the dashboard. Retrieving the trouble codes through an OBD scanner can help pinpoint the IAC car idle motor as the potential issue. You can find an important car diagnostic code, P0505, for a malfunctioning idle air control valve using an OBD scanner.

FAQS

1. IS IT SAFE TO DRIVE WITH A BAD CAR IDLE AIR MOTOR CONTROL VALVE?

Driving with a bad car idle motor (IAC) valve can be risky as it may cause irregular engine idling, stalling, or unexpected shutdowns. These issues can compromise vehicle control and safety, especially in traffic. It's advisable to address the problem promptly to ensure safe driving conditions.

2. HOW TO BYPASS THE CAR IDLE AIR CONTROL VALVE?

Bypassing the Idle Motor Air Control (IAC) valve is generally not recommended because it can lead to engine performance issues. However, if necessary, you can manually set the idle by adjusting the throttle stop screw. This adjustment bypasses the car idle motor IAC's function but should only be done temporarily or in an emergency.

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

Typically, if there is a problem with the IAC car 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 car idle motor or its circuit, a vehicle specific repair manual should be consulted for further testing.
