The actual value is okay.End of test
NO
The actual value is not o.k.Possible cause and remedy
- Check power supply of component B28 (Pressure sensor).
- Test signal voltage of component B28 (Pressure sensor).
Further possible causes of fault
- Vacuum line
2.2. Check power supply of component B28 (Pressure sensor).
