Continuous camshaft adjustment ( RIGHT ): Incorrect position of the exhaust camshaft (P0014)


Possible cause:

- Y49/7 (Right camshaft exhaust solenoid)
- Camshaft position 'Exhaust'
Affected functions:

- Engine diagnosis
- Engine output

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

Test 1: Check component Y49/7 (Right camshaft exhaust solenoid).

Test 2: Check assignment of signals from Hall sensors 'Camshafts' and 'Crankshaft'.

1. Check component Y49/7 (Right camshaft exhaust solenoid).

Test 1.1: Test actuation of component Y49/7 (Right camshaft exhaust solenoid).

Test 1.2: Test current consumption of component Y49/7 (Right camshaft exhaust solenoid).

1.1. Test actuation of component Y49/7 (Right camshaft exhaust solenoid).
Test prerequisite

- Engine at idle
- Vehicle stationary
- Coolant temperature > 80° C
- Time since engine start> 60 s
Status of relevant actual value:
- Temperature of coolant:Warning! Communication with ECU required.
Note

- After the actuation it may be necessary to erase the fault memory!
Proceed to 'Actuation' with F2

1.2. Test current consumption of component Y49/7 (Right camshaft exhaust solenoid).

Test sequence

- Switch off ignition.
- Connect socket box (126-pin) to component N3/10 (ME-SFI [ME] control unit).
- Measure direct current with multimeter between sockets [F.4] 100 and [M.24] 24 of the 126-pole socket box tester.
- Switch on ignition.
Testing of maximum power consumption may be conducted for no longer than 5 s.Specified value

- Amperage[1.0...1.8] A
Question

- Is the measurement value OK?


YES
The measurement value is OK.End of test

NO
The measurement value is not OK.Possible cause and remedy

- K40/4f43 (Fuse 43)
- Line from component Y49/7 (Right camshaft exhaust solenoid) to component Z7/35 (Circuit 87 M1e connector sleeve)
- Line from component Y49/7 (Right camshaft exhaust solenoid) to component N3/10 (ME-SFI [ME] control unit)
- Y49/7 (Right camshaft exhaust solenoid)
End of test







2. Check assignment of signals from Hall sensors 'Camshafts' and 'Crankshaft'.
