WARNING: This page is about a different car, the 2003 Saab 9-3 and 2002 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
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:
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 handling: (For more information, see FAULT HANDLING III, OTHER EMISSION-RELATED COMPONENTS AND FUNCTION ).
- Type III.
