What does this fault code mean?

The ECM monitors the actual idle speed and sets the code when it stays above the limit for a set time. It is a component fault in which the idle control does not work as intended. The cause may be a large leak in the intake system or a blocked intake or exhaust system.

Possible causes

Large leak in the intake system
Blocked intake system
Blocked exhaust system

What you can do

1At high and unsteady idle speed: check that the intake system has no large leaks or damage
2At low and unsteady idle speed: check that the intake and exhaust systems are not blocked
3If you have a diagnostic tool, read the idle speed in live data with the engine idling and see whether the value stays steady
4Clear the code and road test the car, or let the engine idle for a while and see whether the code returns
5If the code returns, have a workshop with diagnostic equipment check the idle control and the intake

Symptoms you may notice2

High idle, either sometimes or all the time
Uneven idle
