P0106
Read the instructions below then
start the fault diagnostic procedure.
Symptom: CHECK ENGINE.
Engine speed drops slower than normal when accelerator pedal is released.
Misfiring can occur before trouble code is generated.

On-Board Diagnostics
Type of diagnosis:
|
-
|
Continuous. But interrupted when fault criteria fulfilled and will not restart until next driving cycle.
|
Enable criteria:
|
-
|
General conditions for this trouble code: When starting the engine, the atmospheric pressure must exceed 78 kPa and the engine coolant and intake air temperatures 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 deviates 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.
|
OK report:
|
-
|
Test 1 and Test 2 performed once and fault criteria not fulfilled. Fault criteria for P0107 or P0108 not fulfilled.
|

Fault handling III, other emission-related components and functions

Diagnostic help
Fault diagnosis concerns sensor fault. A very large vacuum leak can generate the DTC.
Functions in the diagnostic tool related to the fault:
|
•
|
Pressure sensor reading, in kPa. With the engine switched off, this reading should be the same as those for the other two pressure sensors. Permissible variance is 10 kPa.

"Read Values" menu
