Was bedeutet der Fehlercode?

The ECM monitors the vacuum pressure sensor, which measures the negative pressure in the brake booster. If the vacuum is too low while driving, automatic engine start/stop is not allowed. The fault may be a loose or oxidized connector, or a damaged sensor.

Mögliche Ursachen

Loose or oxidized connector contact
Damaged vacuum pressure sensor

Was Sie tun können

1Check that the vacuum pressure sensor connector is secure and not oxidized
2Check that the hose between the engine and the brake booster is secure and not kinked or damaged
3If you have a diagnostic tool, read the vacuum pressure in live data with the engine running and see whether the value is steady
4Clear the code and start the engine to see whether it returns
5Do not work on the brake booster yourself; if the fault returns, have a workshop check the vacuum pressure sensor with diagnostic equipment

Symptome, die Sie bemerken können1

Automatic engine start/stop does not work, both while driving and at idle

Was der Fehler beeinflussen kann2

The module uses a vacuum value that corresponds to no vacuum
Automatic engine start/stop is switched off
