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.
Front bank air pressure sensor P1106
•
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 filter box large connector, the Marelli control unit connector and the sensor con-
nector; if not OK, restore. If everything is OK, check that resistance between VEHICLE
connector PIN 49 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.
Error for unexpected air intake in the rear cylinder manifold P1600
•
signal not plausible.
Error cause
•
Small difference detected between the estimated pressure and the measured pressure: the
measured pressure is higher than the estimated one (for example, the pipe between sensor
and throttle body is squashed or there is a hole in the intake manifold).
