Result

Cause Of Fault
E001 Result: Defective Component
  • Defective component:
    Y164 Solenoid valve - Camshaft, intake
    or
    A84 Control Unit - Engine

Important:

Reset the concerned control unit with the diagnostic tester before replacing it. In order to do that, call up the "RESET" function from the PROGRAMMING menu of the current system on the diagnostic tester.

Note:

The replacement of the components must be done in the listed order.

The system must be checked for proper operation after every replacement.
E002 Result: Mechanical/Hydraulic Fault in Component
  • Repair the concerned mechanical component

Important:

Shavings inside the oil duct may cause the trouble code to be set again.

If shavings in the valve were the cause of the fault, the oil duct must be cleaned as far as possible.
E003 Result: Mechanical/Hydraulic Fault in Component
  • Defective component:
    Y164 Solenoid valve - Camshaft, intake

Important:

If shavings in the valve were the cause of the fault, the oil duct must be cleaned as far as possible.

Shavings inside the oil duct may cause the trouble code to be set again.
E004 Result: Defective Component
  • Defective component:
    Y164 Solenoid valve - Camshaft, intake
E005 Result: Short to Ground/Interruption
  • Short circuit to ground/interruption of circuit between:
    A84 Control Unit - Engine
    Wiring harness connector (wiring harness side) terminal 56 (XC3)
    &
    Y164 Solenoid valve - Camshaft, intake
    Wiring harness connector (wiring harness side) terminal 1
E006 Result: Short to Voltage
  • Short circuit to voltage between:
    A84 Control Unit - Engine
    Wiring harness connector (wiring harness side) terminal 56 (XC3)
    &
    Y164 Solenoid valve - Camshaft, intake
    Wiring harness connector (wiring harness side) terminal 1
E007 Result: Interruption
  • Circuit interruption between:
    X125 Underhood Electronic Module
    Wiring harness connector (wiring harness side) terminal 29 (XE3)
    &
    Y164 Solenoid valve - Camshaft, intake
    Wiring harness connector (wiring harness side) terminal 2

or

  • Defective component:
    X125 Underhood Electronic Module

Important:

Reset the concerned control unit with the diagnostic tester before replacing it. In order to do that, call up the "RESET" function from the PROGRAMMING menu of the current system on the diagnostic tester.
