Am fost cu masina la tester deoarece nu imi mai porneste si mi-a dat urmatoarea eroare: "control, timing device, postion control wrong by +/- 3' crankshaft, currently not present".

Are cineva idee ce inseamna asta, cel care mi-a facut testul mi-a zis ca nu e pompa de injectie bine pusa la punct are eroare +/- 3 gr.

Start of Injection Closed-Loop Control DDE 3.0

.

 

 

Function

The setpoint for start of injection control is derived from following variables for the operating status:

 

• Engine speed
• Injection quantity
• Coolant temperature
• Atmospheric pressure
• Boost pressure
• Fuel temperature

The start of injection is set in the injection pump by means of the timing valve for the injection timing device. The needle movement sensor at cylinder No. 4 signals the actual start of injection back to the DDE control unit. The DDE control unit controls the timing valve of the injection timing device such that the difference between the setpoint and actual start of injection is as low as possible. Fault code 0A "start of injection closed-loop control" is stored if the difference is too great (tolerance depending on operating status approx. +/-2° crank angle). In addition, the position control of the injection timing device is also monitored and fault code 48 "injection timing device control" is stored in the case of fault.

 

 

Troubleshooting

If fault code 0A or 48 is stored, the injection rate is limited to 25 mg/stroke.

 

In this case, the system changes over from start of injection closed-loop control to start of injection open-loop control with fixed duty factor in case of:

 

• Fault code 0A, "start of injection closed-loop control"
• Fault code 2F, "crankshaft position/rpm sensor"
• Fault code 47, "synchronism of rpm sensors"
• Fault code 10, "supply voltage"
• Fault code 5, "needle movement sensor"
• Starting the engine
• Deceleration fuel cutout

Pare a fi injectorul cu fir de la cilindrul nr. 4

 

 

Cate ceva si despre senzorul din injectorul cu fir:

 

 

Needle Movement Sensor DDE 3.0

The needle movement sensor is integrated in the injection nozzle of cylinder No. 4 and cannot be replace separately. The sensor registers the start of injection at cylinder No. 4 which represents the actual value for start of injection control.

 

 

Function

The needle movement sensor consists of a coil which receives a constant, defined current of 30 to 35 mA from the DDE control unit. Movement of the nozzle needle generates a voltage signal that is evaluated by the DDE control unit.

 

 

Troubleshooting

Monitoring requires a battery voltage above 9 V. Fault code 5 "needle movement sensor" is stored if the needle movement sensor is defective.

 

Consequences:

 

• Changeover from start of injection closed-loop control to start of inejction open-loop control
• Exhaust gas recirculation is deactivated
• Injection quantity limited to 25 mg/stroke

Nu e de la injectorul cu fir fiindca a fost si ala schimbat si tot porneste greu...

S-a rezolvat...multumesc Dereglatu

Se poate inchide

Era gaurit un furtun de alimentare al pompei si tragea aer pe instalatie.

Deci s-a rezolvat prin schimbarea furtunului respectiv

care furtun , unde este situat?

Furtunul este undeva sub filtrul de motorina si duce catre pompa de injectie, este dintr-un plastic alb lucios.

Salut,

Am si eu o problema cu un e46.Masina cand porneste, cand nu porneste.Pe test am eroarea" 4293 DDE:Control module , internal 16" Se pare ca este de la calculatorul de injectie.A mai patit cineva?
