What does this fault code mean?

The ECM compares the actual idle speed with the limit and sets the code when the speed stays below the limit for a set time. It is a component fault, showing that the idle control is behaving in an unexpected way. The cause may be a large leak in the intake 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

1Check the intake system for large leaks, such as loose hoses or connections
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 system

Symptoms you may notice2

Low idle, either sometimes or all the time
Uneven idle
