   Oil pressure: 

   Standard 

   88 kPa (0.9 kg/cm ²  , 13 psi) or more at 800 rpm 

   294 kPa (3.0 kg/cm ²  , 43 psi) or more at 5,000 rpm 

   CAUTION:

   • If the oil pressure is out of specification, check oil pump, oil filter and lubrication line. < Ref. to INSPECTION , General Diagnostic Table. >
   • If the oil pressure warning light is turned to ON but oil pressure is within specification, replace the oil pressure switch. < Ref. to INSPECTION , General Diagnostic Table. >
   NOTE: The specified value is based on an engine oil temperature of 80°C (176°F).
8. After measuring the oil pressure, install the oil pressure switch. < Ref. to INSTALLATION , Oil Pressure Switch. >
