On-board diagnosis
Type of diagnosis:
Enable criteria:
| Battery voltage must be between 11 - 16 V. |
| Accelerator pedal released |
| Engine speed higher than 1300 rpm then down to idling speed. |
| Engine load lower than 110 mg/c. |
| NONE of the following DTCs must be detected: P0107, P0108. |
Dependent:
System reaction to a fault:
| Torque limited to max. 170Nm. |
| Boost pressure adaption is blocked and reset. |
| Correction of mass air flow/combustion for fuel calculation is blocked. |
| Limited acceleration and idle function. |
| Secondary air pump not active, if fitted. |
OK report:
| Test 1 and Test 2 completed once and fault criteria not fulfilled. |
Fault handling:
| (See section Fault handling III, "Other emission-related components and functions" for more information.) |
Diagnostic help
Diagnosis regards:
| Electrical fault in the component. |
| Air leak between the throttle and inlet valves or an incorrectly adjusted intake cam. |
| ____________________________________ |
| • | The DTC may also be generated if the camshafts are incorrectly adjusted. |
| ____________________________________ |
| In the event of a rapid release of the accelerator pedal, the intake pressure is checked to ensure that it is below 50 kPa. |
Functions in the diagnostic tool related to the fault:
| • | Manifold absolute pressure sensor |
| (See also description of readings/activations in diagnostic tool) |
