Ducati Diavel Service Manual: Throttle valve operation engine

Introduction

The electric motor actuating the throttle valve for the vertical cylinder is mounted on the throttle body of the diavel, while a link rod connects the vertical cylinder throttle valve to the horizontal cylinder throttle valve. In the electric motor, the throttle valve position sensor (tps) is integrated.

The electric motor, which also incorporates the throttle valve position sensor (tps), is visible on the right, on the throttle body. The accelerator position sensor (aps) is visible on the left.

In the event of fault

In the event of a throttle valve actuator fault, motor power is cut off and the throttle valves close (see chapter relative to ride-by-wire system).

Fault codes generated and possible correlated faults fault codes generated by the engine control unit and displayed by the dds (etv motor diagnosis):

Note

Check integrity of electric circuit - short-circuit to vdc = with dashboard on, using a voltmeter, a voltage is measured between the wire tested and ground.

Check integrity of electric circuit - short-circuit to ground = with the battery cables disconnected, using an ohmmeter, continuity is detected between the wire tested and ground.

Check integrity of electric circuit - open circuit = with the battery cables disconnected, using an ohmmeter, no continuity is detected between the two ends of the wire tested.

The dashboard service display shows the error "etv motor" (throttle valve actuator motor) and the eobd warning light activates.

Possible correlated faults: the engine does not start, cuts out or remains running at idle speed and will not accelerate.

Check:

The throttle valve actuator motor may be actuated into three preset positions (0%, 50%, 100%) using the dds.

If none of the tests described above identify the problem and the throttle valve actuator is in proper working order, contact ducati.

Component replacement methods

The throttle valve actuator motor incorporates the throttle valve position sensor (tps) and cannot be replaced as an individual component. In case it brakes down it will be necessary to fit a new throttle body (refer to sect. 6 - 8, Operating principle and characteristics of the ride-by-wire system). After replacement of the throttle body, reset the self-adaptive parameters relative to carburation with the dds. Adjust the cables connecting the throttle grip to the throttle grip position sensor.

Injectors
Introduction The injectors used on the diavel are top feed units, meaning that fuel is fed into the top of the injector itself. The injectors contain a winding which raises a needle when electrica ...

Refitting the air filters
Apply universal sealant in the air duct (2) and (6) groove (d). Fit seal (7) in the groove (d) having care to place it correctly in the relevant seat so as to avoid abnormal wrinkles. Pull out the filter cartridge (1) from the seat in the airbox. Position the rh air duct (2). Start ...

Removal of the rear wheel eccentric hub and rear wheel shaft
Before removing the eccentric hub, you must first remove the parts listed below. Slacken off the screws (34). Remove the spacer (20) and the inner ring (21) on the chain side and remove the wheel shaft (31) with the brake disc (30) from the opposite side. Remove the circlip (19 ...

Parking
Park the stopped motorcycle on the side stand. Turn the handle completely to the left or right. If this operation is performed within 60 seconds after the engine stop, the message "waiting for lock" (fig. 120) Will appear on the display of the instrument panel for approx. 5 Seco ...
