Conditions for Setting the DTC

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.
• The above condition is present for greater than 10 s.
