YES

The actual value is okay.Further possible causes of fault

- Check internal resistance of component B2/5b1 (Intake air temperature sensor).

NO

The actual value is not o.k.Possible cause and remedy

- Signal wire

End of test

2.3. Check internal resistance of component B2/5b1 (Intake air temperature sensor).

Test sequence

- Switch off ignition.

- Detach coupling at component B2/5 (Hot film mass air flow sensor).

- Measure resistance with multimeter between pins (B2/5) 2 and (B2/5) 3
