•
Short-circuit to positive: excessive voltage has been detected on PIN 49. If open circuit, short
circuit to negative: voltage equal to zero detected at PIN 49.
Troubleshooting
•
Short-circuit to positive: check on the diagnostic tool if the parameter of the rear cylinders
air Pressure Sensor reads approx. 1,200 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, re-
place the sensor.
•
If open circuit, short circuit to negative: check the Marelli control unit connector and the
sensor connector; if not ok restore, if everything is OK, with key OFF, check the continuity
between Marelli control unit connector PIN 49 and sensor connector PIN 3: if there is no
continuity, restore the wiring harness, if there is continuity, check the ground insulation of
the cable: if there is continuity to ground, restore the wiring harness, if there is no continuity,
check (with key in ON position) that there is a voltage of approx. 5 V present at PIN 1 on the
sensor connector: if not ok turn the key to OFF and check continuity between ENGINE
connector PIN 25 and PIN 1 on the sensor connector: if not OK, restore the wiring harness;
if OK, replace the control unit; if a voltage of 5 V is present at PIN 1, check (with key in ON
position) for continuity between PIN 3 on the sensor connector and ground: if not OK, restore
the wiring harness; if OK, replace the sensor.
DIAGNOSTIC TOOL: LOGIC ERRORS
Rear bank air pressure sensor P0106
•
signal not plausible.
Error cause
•
An average value of the intake pressure is estimated based on the engine operating data
(rpm, throttle valve, …): if the read value differs with a certain percentage, then this error is
activated. The most frequent cases can be: abnormal resistance in the sensor circuit (for
example, rusted terminals) or sensor with poor performance.
Troubleshooting
•
check the Marelli control unit connector and the sensor connector; if not OK, restore. If
everything is OK, check that resistance between VEHICLE connector PIN 24 and sensor
connector PIN 3 is a few tenths of an Ohm; If it is above that value, restore cable harness.
Replace the sensor if it is correct.

signal not plausible.
Error cause
