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:


- 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 differs 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. 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: (For more information, see .)


- 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.
