ELECTRICAL SYSTEM
Workshop Manual Ed. 07-2012
Ignition and starter system (TE-TXC)
The engine injection and starter system is controlled by the control unit (ECU);
by means of a series of sensors, the ECU controls the status of the engine and
of the surrounding environment at each given moment.
These are : a crankshaft position sensor (pick-up), an ambient air temperature
sensor in filter box and a group of sensors providing information relating to pres
-
sure, air temperature and butterfly valve opening position.
Moreover, the ECU uses a lambda probe for the constant adjustment of the air-
fuel ratio (Euro3 mode).
