Hva betyr feilkoden?

On a cold start the ECM raises the idle speed to warm the catalytic converter up to working temperature. The code is set when the actual idle speed stays above the limit for a set time. This is a component fault in which the idle control does not work as intended. An air leak in the intake system may be the cause.

Mulige årsaker

Air leak in the intake system

Hva du kan gjøre

1Check the intake system for air leaks at the hoses and at the connections to the intake manifold
2Note whether the high idle is present when the engine is cold or also when it is warm. A higher idle during warm-up is intentional
3If you have a diagnostic tool, read the idle speed in live data during a cold start and see how it changes during warm-up
4Clear the code and road test the car, or let the engine cool and start it again to see whether the code returns
5If the code returns, have a workshop with diagnostic equipment check the intake system for leaks

Symptomer du kan merke2

High idle, either sometimes or all the time
Uneven idle
