Ducati Diavel Service Manual: Component assembling position

Component assembling position


The throttle valve position sensor is integrated in the throttle valve actuator motor.

Component assembling position


Location of electric connection for throttle valve actuator motor - tps (throttle valve position sensor).

Connection wiring diagram

Connection wiring diagram


Ccm engine control connection, s throttle valve position sensor. Main potentiometer p: 3 signal, orange/blue - o/b, secondary potentiometer s: 1 signal, orange/green - o/g, 4 common ground, black/yellow bk/y, 2 common power (5v), brown/yellow - bn/y.

In the event of fault

In the event of a throttle valve position sensor fault, the ecu disables the ride-by-wire system and the engine will not start, remains running at idle or stops.

Fault codes generated and possible correlated faults

Fault codes generated by the engine control unit and displayed by the dds (throttle position sensor 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 "throttle position" 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.

The dds may be used to read the throttle valve position value.

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

Component replacement methods

The throttle valve position sensor is integrated into the throttle valve actuator motor 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 this section 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.

Throttle valve position sensor
Introduction The throttle valve position sensor (tps) of the diavel is mounted on the throttle body. The sensor is integrated into the throttle valve actuator motor, which turns the spindle ...

Air temperature sensor
Introduction The engine control system on the diavel uses a sensor that measures air temperature. This sensor has a resistance of ntc type (negative temperature coefficient), that reduces its own ...

Adjusting the chain tension
Make the rear wheel turn until you find the position where chain is tightest. Set the vehicle on the side stand. Push down the chain at the point of measurement and release. Measure the distance between the "aperture" upper profile and pin centre. The read distance must be: 9 to 11 mm. ...

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 On ...

Passive key
Introduction The passive key (1) is used when the active key is not working correctly or is not available. The passive key works as a transponder, and must therefore be placed physically onto the antenna to work. The mechanical part (2) of the key is used to open the seat or the tank plug ...
