Co oznacza ten kod błędu?

On a cold start the ECM raises the idle speed to warm the catalytic converter. The code is set when the actual idle speed stays below the limit for a set time, that is, even though the idle should be higher during warm-up. A blocked intake or exhaust system may be the cause.

Możliwe przyczyny

Blocked intake system
Blocked exhaust system

Co możesz zrobić

1At low and unsteady idle speed: check that the intake and exhaust systems are not blocked
2Check that the air filter is not clogged and that the intake is free from objects
3If you have a diagnostic tool, read the idle speed in live data during a cold start and see whether it rises 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 and exhaust systems and the idle control

Objawy, które możesz zauważyć3

The check engine lamp lights or behaves abnormally
Low idle, either sometimes or all the time
Uneven idle
