A L L Diagnostic Trouble Codes ( DTC ): Manufacturer Code Charts 0281
Component Y49/4 (Left camshaft intake solenoid) has a short circuit to positive. (P2093)
Possible cause:
- Y49/4 (Left camshaft intake solenoid) Affected functions:
- Engine diagnosis - Engine output
------------------------------------------------
Test 1: Check component Y49/4 (Left camshaft intake solenoid).
1. Check component Y49/4 (Left camshaft intake solenoid).
Test 1.1: Test actuation of component Y49/4 (Left camshaft intake solenoid).
Test 1.2: Test current consumption of component Y49/4 (Left camshaft intake solenoid).
1.1. Test actuation of component Y49/4 (Left camshaft intake 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 Y49/4 (Left camshaft intake solenoid). Figure legend

Test sequence
- Measure direct current with multimeter between sockets [F.4] 100 and [M.48] 48 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
- N10/1f43 (Fuse 43) - Line from component Y49/4 (Left camshaft intake solenoid) to component N3/10 (ME-SFI [ME] control unit) - Y49/4 (Left cam
