3.1.3 Bosch MED 7.6.1 ECU operating logic

The 1.9 and 2.2 JTS engines are characterised by a fuel feed system with high pressure direction injection pump.
The electronic control system governs and controls all engine parameters, optimising performance and consumption
by providing real time response in various operating modes.
The system is managed by a single Bosch Motronic MED7.6.1 driven throttle ECU that controls sequential and timed
ignition and injection.
The ECU controls the actuators on the basis of the signals received from numerous sensors and governs the
following systems:
fuel system
high pressure fuel pump
air supply
accelerator pedal
engine cooling
exhaust with catalytic converters controlled by four lambda sensors
fuel vapour recirculation.
