P0521

• The ECM detects that the difference between the predicted oil pressure and the actual oil pressure is either less than 47 kPa (6.8 psi) or greater than 50 kPa (7.3 psi).
• The engine oil pressure is outside of a calculated working range determined by engine speed and temperature.
• The above condition is present for greater than 10 s.

P0522

• The ECM detects that the engine oil pressure sensor signal circuit is less than 0.2 V.
• The above condition is present for greater than 10 s.

P0523

• The ECM detects that the engine oil pressure sensor signal circuit is greater than 4.8 V.
