Charge Air Absolute Pressure Sensor Circuit. Performance Problem.







Fault symptom
CHECK ENGINE

On-board diagnosis

Type of diagnosis:
Continuous

Enable criteria:
Battery voltage must be between 11 - 16 V.
NONE of the following DTCs must be detected: P0107, P0108, P0237, P0238, P2228 and P2229.
Ignition ON.
Vehicle speed 0 km/h.
Engine speed 0 rpm.
The conditions above must be fulfilled for more than 3 s, after which the engine must be running for the diagnosis to finally run.

Fault criteria:
Absolute pressure sensor value differs more than 12 kPa from atmospheric pressure sensor and manifold absolute pressure sensor.

Dependent:
None

System reaction to a fault:
Torque limited to max. 140 Nm.
Boost pressure adaption blocked.
The control module uses a substitute value that is a function of atmospheric pressure, engine speed and damper area.

OK report:
Fault criteria above NOT fulfilled.

Fault handling:
Type III
(See Description of On-Board Diagnostics/Fault handling III, "Other emission-related components and functions" for more information.)

Diagnostic help

Diagnosis regards:
Electrical fault in connecting leads or component.

Functions in the diagnostic tool related to the fault:
Pressure sensor value, unit kPa. When engine stationary, value must agree with values of two other pressure sensors. Permitted difference is 10 kPa.
