Manufacturer Code Charts: 124600

The supply voltage to the sensors is outside the valid range.


Possible cause:

- Supply voltage
Affected functions:

- Power generation

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

Test 1: Supply voltage Test sensor 1.

1. Supply voltage Test sensor 1.

Test 1.1: If fault codes for several sensors are displayed at the same time, then one sensor has a short circuit to GND or to POS at the component or at the lead.

Test 1.2: Check component B4/6 (Rail pressure sensor).

Test 1.3: Check component M16/6 (Throttle valve actuator).

1.1. If fault codes for several sensors are displayed at the same time, then one sensor has a short circuit to GND or to POS at the component or at the lead.

1.1. No further information available.


1.2. 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

1.3. Check component M16/6 (Throttle valve actuator).

- M16/6 (Throttle valve actuator)
- B5/1 (Boost pressure sensor)
Possible cause and remedy

- Inspect wiring and plug connections between M16/6 (Throttle valve actuator) and control unit N3/9 (CDI control unit) for corrosion, loose contacts and damage.
- Test wiring and plug connections between control module N3/9 (CDI control unit) and M16/6 (Throttle valve actuator) for Short circuit and Open circuit, repair or replace if necessary.
