Hva betyr feilkoden?
The control module keeps checking whether the boost sensor reading matches how the sensor should behave. If the signal becomes uneven or falls outside reasonable values, a fault is logged and the control module uses a calculated boost pressure instead. The cause is poor contact in the connections or a damaged sensor.
Mulige årsaker
- Loose connection, contact resistance or oxidation in the connections
- Damaged boost pressure sensor
Hva du kan gjøre
- 1Read the fault code, clear it and road test to see whether it returns
- 2Check the boost pressure sensor connector: is it fully engaged and free from oxidation?
- 3Follow the cable from the sensor and look for chafing, pinched sections and loose clips
- 4If you have a diagnostic tool, check in live data whether boost pressure changes smoothly as the accelerator is pressed and released
- 5If the fault returns after a road test, have a workshop decide whether the boost pressure sensor should be replaced
Symptomer du kan merke1
- Check engine light comes on or behaves abnormally
Hva feilen kan påvirke1
- A calculated boost pressure is used instead
