Result |
Cause Of Fault |
E01 |
• Defective component: Vacuum hose or P23 Sensor - Absolute Pressure, Intake Manifold Note: Check the hoses for leakage or blockage before replacing the component. |
|
|
E02 |
• Short circuit to ground/interruption of circuit between: P23 Sensor - Absolute Pressure, Intake Manifold Wiring Harness Connector Terminal B & K57 Control Unit - Multec Wiring Harness Connector Terminal A7 or • Defective component: K57 Control Unit - Multec |
|
|
E03 |
• Short circuit to voltage between: P23 Sensor - Absolute Pressure, Intake Manifold Wiring Harness Connector Terminal B & K57 Control Unit - Multec Wiring Harness Connector Terminal A7 or • Defective component: K57 Control Unit - Multec |
|
|
E04 |
• Short circuit to voltage/interruption of circuit between: P23 Sensor - Absolute Pressure, Intake Manifold Wiring Harness Connector Terminal A & K57 Control Unit - Multec Wiring Harness Connector Terminal D15 or • Defective component: K57 Control Unit - Multec |
|
|
E05 |
• If the nominal value is reached during one of the measurements, the component/control unit that has been disconnected immediately before that measurement is defective. |
|
|
E06 |
• If the nominal value is not reached with any of the measurements, this indicates that one of the following faults is present: Short to voltage/ground/interruption of circuit between: P23 Sensor - Absolute Pressure, Intake Manifold Wiring Harness Connector Terminal C & K57 Control Unit - Multec Wiring Harness Connector Terminal D8 or Defective component: K57 Control Unit - Multec |
