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.

P0106

Fault symptoms

•	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 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:

-	P0336 and P0337.

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 for P0107 or P0108 not fulfilled.

Fault handling: (For more information, see .)

-

Type III.

Diagnostic help

Fault diagnosis concerns sensor fault. A very large vacuum leak can generate this diagnostic trouble code.

Functions in the diagnostic tool related to the fault:

•	Pressure sensor value, unit kPa. The value should correspond with the other two pressure sensors when the engine is stationary. Accepted difference is 10 kPa.
