Hva betyr feilkoden?
The boost pressure sensor (TMAP) measures both boost pressure and temperature. The fault code is set when the temperature signal is unreasonably low. Possible causes are a poor connection or a damaged sensor.
Mulige årsaker
- Loose connection, contact resistance or oxidation in the connector
- Damaged boost pressure sensor (TMAP)
Hva du kan gjøre
- 1Check that the boost pressure sensor connector is fully seated and free from oxidation
- 2Look for cracks or damage on the sensor housing and the wire
- 3If you have a diagnostic tool: after the engine has been off for a longer period, read the sensor temperature in live data and compare it with the ambient temperature
- 4If the connector is in good condition but the temperature still differs, have a workshop check the boost pressure sensor
Symptomer du kan merke1
- No noticeable symptoms for the driver
Hva feilen kan påvirke1
- The engine control module uses a calculated value instead of the measured temperature
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
