DORSODURO FACTORY ABS
front cylinder air pressure sensor P0107 - signal not valid.
Error cause
•
According to the engine operation data (rpm, throttle, etc.) an average value for the intake
pressure is estimated: if the value read deviates by a given percentage, this error is activa-
ted. The most frequent causes 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 cable resistance between VEHICLE
connector PIN 34 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.
rear cylinder air pressure sensor P0108 - signal not valid.

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 5 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 intake air in the front cylinder manifold P0210 - signal not valid.
Error cause
•
A small difference between the estimated pressure and the measured pressure has been
detected: the measured pressure is higher than the estimated one (for example, cut or
wrongly connected pipe between sensor and throttle body or a hole in the intake manifold).
Troubleshooting
•
Check the pneumatic system between the pressure sensor and the socket to read pressure
on the throttle body; check that the intake manifold is in good conditions and the pressure
reading hole is clean.
Error for unexpected intake air in the rear cylinder manifold P0211 - signal not valid.
Error cause
•
A small difference between the estimated pressure and the measured pressure has been
detected: the measured pressure is higher than the estimated one (for example, cut or
wrongly connected pipe between sensor and throttle body or a hole in the intake manifold).
