On-Board Diagnostics

Type of diagnosis:

Continuous. But interrupted when fault criteria fulfilled and will not restart until next driving cycle.

Enable criteria:

General condition for this diagnostic trouble code: Atmospheric pressure must exceed 72 kPa as well as coolant and intake air temperature must exceed -7°C.
Test 1: Crankshaft stationary, even after ignition OFF. Car stationary. The difference in pressure between the other two absolute pressure sensors in the system less than 10 kPa.
Test 2: Engine running. Engine speed above 1300 RPM. Engine load lower than 110 mg/c. Accelerator pedal fully released.

Fault criteria:

Test 1: Sensor value differs more than 15 kPa from atmosphere absolute pressure sensor.
Test 2: Sensor value exceeds 50 kPa.

Dependents:

System reaction to a fault:

Purging blocked. Correction of air mass/combustion for fuel calculation blocked.
Charge air adaptation blocked and zeroed.

OK report:

Test 1 and Test 2 performed once and fault criteria not fulfilled. Fault criteria forP0107 orP0108 not fulfilled.
