This code means the idle control system is letting the engine idle faster than the computer wants it to. It's commonly caused by a vacuum leak letting in extra air, a stuck or dirty throttle, or a faulty idle air control valve. Finding and sealing vacuum leaks or cleaning the throttle body usually brings the idle back to normal.
$120 – $400
Varies by vehicle and root cause.
Usually yes. A high idle isn't an immediate danger, but the car may creep at stops and waste fuel, so it's best to get it checked before it gets worse.
Repairs typically range from $120 to $400. Cleaning the throttle body is cheap, while sealing vacuum leaks or replacing the idle air control valve costs more.
It's a moderate issue. It won't usually leave you stranded, but a high idle wastes fuel and can make the car harder to control at low speeds, so it's worth addressing soon.
The most common reason is a vacuum leak letting in extra air the computer didn't account for, which raises the idle. A dirty throttle body or faulty idle control valve can do the same.
