P1106

Read the instructions below then start the fault diagnostic procedure.

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

P1106

Fault symptoms

•	CHECK ENGINE.

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

On-Board Diagnostics

Type of diagnosis:

-	Continuous. However, it is interrupted once the fault criteria have been fulfilled and does not restart until the next driving cycle.

Enable criteria: (Conditions that must be fulfilled for diagnostics to be performed.)

-	Global conditions for this diagnostic trouble code: When starting the engine, the atmospheric pressure must exceed 78 kPa and the temperature of the coolant and the intake air must exceed -7°C.

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

Fault criteria: (When enable criteria have been fulfilled, diagnostics will check if the fault criteria have been fulfilled.)

-	The sensor reading deviates more than 15 kPa from the atmospheric absolute pressure sensor.

Dependents: (Once fault criteria have been fulfilled, a number of other diagnostics must report OK before the diagnostic trouble code can finally be generated.)

-	P0336 and P0337.

System reaction to a fault: (Once the fault criteria have been fulfilled, certain measures will sometimes be taken.)

-	Density compensation of the throttle angle is blocked.

OK report: (This diagnosis may be included as a dependent to another diagnosis and must therefore report OK even if it is continuous. The OK report is also used in fault handling to count down the fault counter.)

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

Fault handling: (Refer to section “Fault diagnosis, general” for more information.)

-

Type III.

Diagnostic help

Fault diagnosis concerns a malfunction in the sensor.

Diagnostic tool functions related to this fault:

•	Pressure sensor reading, unit kPa.

When the engine is stationary, the value should correspond with that of the other two pressure sensors. Permissible difference is 10 kPa.
