Order of inspection
P0520 Engine Oil Pressure Sensor/Switch Circuit High
The P0520 code means the engine oil pressure sensor circuit is not responding the way the computer expects. Before you assume it is an electrical fault, rule out that the pressure is really too low, because being wrong here is serious and cannot be undone. Check the oil level first, then confirm with a mechanical gauge.
