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


Charge Air Absolute Pressure Sensor Circuit. Performance Problem.

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:


- 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.

- 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.


OK report:


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


Fault handling: (See section Fault handling III, other emission-related components and functions for more information.)


- Type III.


Diagnostic help

Fault diagnosis concerns sensor fault.

Functions in the diagnostic tool related to the fault:


• 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.

See also description of readings under "Read Values" menu for more information.
