Ducati Diavel Service Manual: Introduction to the engine control system

The engine control system used on the diavel consists of the following elements:

• Ride-by-wire system (motorised throttle valves with electric actuator, throttle grip position sensor and throttle valve position sensor)
• One injector per cylinder installed downstream of throttle valve
• One coil per cylinder, in spark plug bore
• Two oxygen sensors (one per cylinder, installed on each exhaust manifold)
• Two absolute pressure (map) sensors installed downstream of throttle valve (one per cylinder connected to each intake duct)
• One three-way catalytic converter for exhaust gas post-treatment

The system also includes conventional sensors for water and air temperature, engine speed-timing etc.
