Inspection Procedure

HINT:

If there is an open or short in the engine coolant temperature sensor circuit, the ECM outputs DTCs. Perform troubleshooting with the "SFI System" (See DTC CHECK / CLEAR ).

1. PERFORM ACTIVE TEST BY INTELLIGENT TESTER 
   1. Operate the intelligent tester according to the steps on the display and select the "ACTIVE TEST".

      METER: 

      METER REFERENCE
      
      

      Item	Test Details	Diagnostic Note
      COOLANT TEMP	LOW / NORMAL / HI	-

   OK: 

   Needle indication is normal. 

   NG: REPLACE COMBINATION METER ASSEMBLY 

   OK: GO TO NEXT STEP 

2. READ VALUE OF INTELLIGENT TESTER (ENGINE COOLANT) 
   1. Operate the intelligent tester according to the steps on the display and select the "DATA LIST".

      ENGINE: 

      ENGINE REFERENCE
      
      

      Item	Measurement Item / Display (Range)	Normal Condition	Diagnostic Note
      COOLANT TEMP	Coolant Temperature / Min.: - 40°C (-40°F), Max.: 140°C (284°F)	After warming up: 80 to 95°C (176 to 203°F)	If the value is "-40°C (-40°F)" or "140°C (284°F)", sensor circuit is open or shorted.

   OK: 

   Coolant temperature displayed on the tester is between 80°C (176°F) and 95°C (203°F) after warming up.
