DTC P0524-00: Engine Oil Pressure Too Low [09/2022 - ]: Procedure

Refer to ON-VEHICLE INSPECTION [09/2022 - 08/2023] , or refer to ON-VEHICLE INSPECTION [08/2023 - ]

1. Check the state of the oil level warning.

   Result

   Result	Proceed to
   Engine oil level is within the specified range and oil level warning is not displayed	A
   Engine oil level is low and oil level warning is displayed	B

   HINT: 

   If the oil level warning is not displayed even though the engine oil level is below the Low mark, or the oil level warning is displayed even though the engine oil level is within the specified range, inspect the oil level sensor and related parts.

Result: 

B

See step  9

1. Install the oil pressure gauge with adapter.

   Refer to ON-VEHICLE INSPECTION [09/2022 - ]

2. Start the engine.
3. Maintain "Coolant Temperature" at 90 to 95°C (194 to 203°F) for 3 minutes, and then read the oil pressure gauge value at 1000 RPM, 2000 RPM and 3000 RPM.

   Powertrain > Engine > Data List 

   Tester Display
   Engine Speed
   Coolant Temperature

   HINT: 

   • When the engine oil pressure and temperature sensor is removed, the engine oil temperature cannot be checked, so refer to "Coolant Temperature".
   • Race the engine as necessary to maintain "Coolant Temperature" at 90 to 95°C (194 to 203°F).
   • If maintained for 3 minutes or more, the engine oil temperature may exceed 85°C (185°F).
   STANDARD
   
   

   Engine Speed	Coolant Temperature	Engine Oil Pressure Gauge Value
   1000 RPM	Maintained at 90 to 95°C (194 to 203°F) for 3 minutes (Reference) Engine oil temperature: 75 to 85°C (167 to 185°F)	85 kPa (0.9 kgf/cm 2 , 15 psi) or higher
   2000 RPM		135 kPa (1.4 kgf/cm 2 , 29 psi) or higher
   3000 RPM		230 kPa (2.3 kgf/cm 2 , 44 psi) or higher

   HINT: 

   Be sure to clear the DTCs after reinstalling the oil pressure sensor (engine oil pressure and temperature sensor) or reconnecting the oil pressure sensor (engine oil pressure and temperature sensor) connector, as DTCs may be stored.
