Boost Pressure Sensor Plausibility

Test 1 - 2:

Test 3 - 5:

SYMPTOM
P0105-BOOST PRESSURE SENSOR PLAUSIBILITY

WHEN MONITORED
With the engine speed below 800 rpm.

SET CONDITION
When the engine is idling, the boost pressure sensor input differs from the barometric pressure sensor input by 2.17 psi for at least 6 seconds.

POSSIBLE CAUSES
- Intermittent condition
- High resistance in the boost pressure sensor signal circuit
- High resistance in the boost pressure sensor ground circuit
- High resistance in the sensor reference voltage B circuit
- Boost pressure sensor
- Engine control module
