   2. Warm up and stop the engine, then wait for 5 minutes.

   3. Check that the engine oil level is between the low level and full level marks on the engine oil level dipstick.

      If the level is low, check for engine oil leaks and add engine oil to the full level mark.

      Note

      Do not fill to above the full level mark.

2. CHECK ENGINE OIL QUALITY

   
   

   1. Check the engine oil for deterioration, water intrusion, discoloration or thinning.

      If the quality is visibly poor, replace the engine oil and oil filter element.

3. INSPECT OIL PRESSURE

   
   

   1. Remove the engine oil pressure switch assembly.

      CAUTION:

      Make sure the engine is cold when removing the engine oil pressure switch assembly to prevent burns caused by hot engine oil.

   2. 

      Install an oil pressure gauge with the adapter.

   3. Put the engine in inspection mode (maintenance mode).

   4. Warm up the engine.

      Tech Tips

      After warming up the engine, the engine coolant temperature is 75 to 100°C (167 to 212°F).

   5. Check the oil pressure.

      Standard Oil Pressure
      Engine Condition Oil Pressure 1000 rpm 145 kPa (1.5 kgf/cm2, 21 psi) or higher 2500 rpm 340 kPa (3.5 kgf/cm2, 49 psi) or higher

      If the result is not as specified, check the quality of the engine oil and check the oil paths for clogging. Repair or replace if necessary. If the engine oil pressure is still not as specified, check the timing chain cover sub-assembly.

   6. Remove the oil pressure gauge with the adapter.

      CAUTION:

      Make sure the engine is cold when removing the engine oil pressure switch assembly to prevent burns caused by hot engine oil.

   7. Install the engine oil pressure switch assembly.
