intake air pressure sensor
Location:
•
on the vehicle: inside the filter housing
•
connector: on the sensor
Pins:
1. Power supply
2. Ground
3. Output signal
DIAGNOSTIC TOOL: PARAMETERS
Front cylinder intake sensor
Example value: 1003 mbar
Pressure read through the front sensor.
Rear cylinder intake sensor
Example value: 1004 mbar
Pressure read through the rear sensor.
Front cylinder intake estimated pressure
Example value: 1003 mbar
Pressure estimated by the control unit, based on the throttle valve position
Rear cylinder intake estimated pressure
Example value: 1004 mbar
Pressure estimated by the control unit, based on the throttle valve position
DIAGNOSTIC TOOL: ELECTRICAL ERRORS
P0105 Front cylinder air pressure sensor
Electrical diagnosis:
•
short circuit to positive / open circuit, short circuit to negative, signal not plausible.
Error cause:
•
Short-circuit to positive: excessive voltage detected at PIN 24 of the Marelli ECU detected.
•
If open circuit, short circuit to negative: voltage equal to zero detected at PIN 24 of the Marelli
ECU.
This error is indicated by the steady on MI indicator light.
Troubleshooting:
•
Short-circuit to positive: on the diagnostic tool, observe the front cylinder air pressure sensor,
which will display a value of approx. 1200 mbar; disconnect the sensor connector: if the
value does not change, this means there is a short circuit in the cable between the control
unit connector and the sensor connector; restore the wiring harness; if the value changes,
replace the sensor.
