The signal voltage of component B4/6 (Rail pressure sensor) is too low.


Possible cause:

- B4/6 (Rail pressure sensor)
Affected functions:

- Power generation

-------------------------------------------------

Test 1: Check component B4/6 (Rail pressure sensor).

1. Check component B4/6 (Rail pressure sensor).
Important note:Reset quantity mean value adaptation data after replacing the following components:(Control unit adaptations/Reset quantity mean value adaptation data.)

- B2/6 (Left hot film mass air flow sensor)
- B2/7 (Right hot film mass air flow sensor)
- B4/6 (Rail pressure sensor)
- G3/2 (Oxygen sensor upstream of catalytic converter)
- Air filter
Communication with ECU required
