Test the oil pressure regulation

This function is used to control the oil pump control valve and thus change the oil pressure.
The control valve determines the size of the pump housing and can thereby control the flow from the oil pump.
Nota:
At 0 % regulation, the oil pressure is high. At 100 % regulation, the oil pressure is low. If the pressure would fall below 260 kpa, the engine control unit will start the piston cooling with fixed intervals. Then will the oil pressure temporarily rise above normal level.

  3. The oil pressure is controlled in different steps with five seconds interval according to the following cycle: 20%, 40%, 60%, 80%, 60%, 40%, and 20%.
  4. Função completa.
