Suzuki SX4 S-Cross year 2015 engine D16AA 88kw (same engine as giulietta 1.6 mjet2)

The car has the error P1541 (correlation voltage solenoid valve oil pump variable/oil pressure switch 2).Deleting it reappears after a few days.the car runs very well,I have just done the 3rd service (in advance as it has 45,000 km).I have already cleaned the solenoid valve oil pump control and checked it (it is on/off and works regularly).are there any known problems of jamming of the pump variable displacement?possible solutions?thanks
