Priklopil sem ga na računalnik, ki mi je pokazal naslednjo napako: 00542 Needle lift sensor (G80).
potem sem poskušal googlati na vse mogoče načine in nalatel na tole:
The injector of the 3rd cylinder is equipped with a needle lift sender (G80) for registering
the point of commencement of injection.
The sender signals the actual opening time of the injector to the control unit. This
signal provides the control unit with feedback on whether the point of commencement
of fuel injection conforms to the map.
Function
Needle lift sender G80 is a solenoid and is supplied with a constant current by the control unit. This produces a magnetic field. A pressure pin inside the solenoid forms an extension to the end of the injector needle. The movement of the injector needle alters the magnetic field and causes distortion of the DC voltage applied to the solenoid.
The control unit calculates the actual point of commencement of fuel injection from the time difference between the needle lift pulse and the TDC signal supplied by the engine speed sender. At the same time, the system compares the actual point of commencement of injection with the setpoint stored in the control unit and corrects any deviations from the setpoint.
Substitute function
If the needle lift sender fails, an emergency running program is started. In this program,
the commencement of fuel injection is controlled according to fixed setpoints
as defined in a map. The injection quantity reduced in addition.
Iz tega mi je nekako jasno da naj bi bilo nekaj narobe z injektorjem na tretjem celindru, mi lahko kdo mogoče razloži kako to zgleda in kako se ta napaka odprav?
Najlepša hvala!
