Fault symptom
Fault indicator lamp (for further information see WIS Fault diagnosis, general)
Performance loss.
On-board diagnosis
Type of diagnosis:
Enable criteria:
Fault criteria:
| The difference between boost pressure and atmospheric pressure is more than 15 kPa for more than 20 s. |
System reaction to a fault:
| Limp Home, engine torque limitation. |
| EGR control and boost pressure control switched off. |
| The control module uses substitute value 101,3 kPa. |
Checking the wiring harness
| • | Faults in the control module female connector can be the cause of the DTC. Check the connector with respect to oxidation, depressed pins and pin clamping force. |
| • | Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force. |
