Hva betyr feilkoden?
Brake pressure sensor 1 tells the ABS control module the pressure in the brake system. This code applies only to cars with stability control. At some point the module registered a faulty signal from this sensor, and the fault is intermittent, meaning temporary. The equivalent code for brake pressure sensor 2 is ABS-00A5.
Mulige årsaker
- Open circuit in the wiring
- Wiring shorted to ground or supply voltage
- Sensor incorrectly fitted
- Faulty pressure sensor or, less commonly, a faulty control module
Hva du kan gjøre
- 1Check that the wiring to brake pressure sensor 1 is intact and not chafed or pinched
- 2Check that the sensor is correctly fitted
- 3Follow the wire to the sensor and look for intermittent open circuits
- 4Remedy as necessary and clear the code
- 5If the fault returns, have a workshop with diagnostic equipment check the pressure signal
- 6ABS and stability control are safety-critical – do not work on the brake system yourself, have a workshop do it
Symptomer du kan merke3

Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
