DORSODURO FACTORY ABS
•
A small difference between the estimated pressure and the measured pressure has been
detected: the measured pressure is below the estimated one (for example, smeared throttle
body).
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.
Engine temperature sensor
ENGINE TEMPERATURE SENSOR
Function
tells the engine temperature to the control unit so
as to optimise its operation.
