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.

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.
