P1106

Read the instructions below then start the fault diagnostic procedure.

Symptom: CHECK ENGINE. Engine speed drops slower than normal when accelerator pedal is released.

P1106

Fault symptoms

•	CHECK ENGINE.

•	Engine speed drops slower than normal when accelerator pedal is released.

On-Board Diagnostics

Type of diagnosis:

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

Enable criteria:

-	Crankshaft stationary, even after ignition OFF. Car stationary. The other two absolute pressure sensors deviate less than 10 kPa from each other.

Fault criteria:

-	Sensor value deviates more than 15 kPa from atmosphere absolute pressure sensor.

Dependents:

-	P0336 and P0337.

System reaction to a fault:

-	Density compensation of the throttle angle is blocked. The charge air adaptation is blocked and zeroed, as a substitute value the atmospheric pressure sensor is used.

OK report:

-	Fault criteria for P1106, P1107 or P1108 not fulfilled.

Fault handling: (See “Fault diagnosis, general” for more information.)

-

Type III.

Diagnostic help

Fault diagnosis concerns sensor fault.

Functions in the diagnostic tool related to the fault:

•	Pressure sensor value, unit kPa.

With the engine stationary, the value should correspond with the two other pressure sensors. Accepted difference is 10 kPa.
