P1106

Read the instructions below then start the fault diagnostic procedure.

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

P1106


Charge Air Absolute Pressure Sensor Circuit. Performance Problem.



Fault symptoms


CHECK ENGINE.

Engine speed drops slower than normal when the accelerator 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, the atmospheric pressure sensor is used as a substitute value.


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.

Diagnostic tool functions related to this fault are:


Pressure sensor reading, in kPa.


With the engine switched off, the reading should correspond with those of the other two pressure sensors. Permissible difference is 10 kPa.
