Co oznacza ten kod błędu?
The ECM monitors the brake vacuum sensor reading, which sits in the power brake booster. The code is stored when the reading stays too high for a period. Possible causes are a signal wire shorted to supply voltage or a damaged sensor.
Możliwe przyczyny
- Signal wire short-circuited to supply voltage
- Damaged brake vacuum sensor
Co możesz zrobić
- 1If you have a diagnostic tool, read the brake vacuum sensor value in live data with the engine running and see whether it is unusually high
- 2Check that the relevant fuses are intact
- 3Check the connector at the brake vacuum sensor for contact resistance and oxidation
- 4Use a multimeter to check that the signal wire to the brake vacuum sensor is not short-circuited to plus
- 5If the fault remains, have a workshop check the brake vacuum sensor, since it sits in the brake booster, which is part of the braking system
Objawy, które możesz zauważyć1
- No noticeable symptoms for the driver
Na co może wpływać usterka1
- The automatic engine start/stop function is switched off
