Engine Coolant Temperature Receiver Gauge Malfunction: Procedure
- PERFORM ACTIVE TEST USING TECHSTREAM (WATER TEMPERATURE METER OPERATION)
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Enter the following menus: Body Electrical / Combination Meter / Active Test.
- Check the operation by referring to the values in the table below.COMBINATION METER:
Tester Display Test Part Control Range Diagnostic Note Water Temperature Meter Operation Engine coolant temperature receiver gauge Low, Normal, Hi - OK
Needle indication is normal.
NG → REPLACE COMBINATION METER ASSEMBLY
OK: Go to next step
- READ VALUE USING DATA LIST (COOLANT TEMPERATURE)
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Enter the following menus: Body Electrical / Combination Meter / Data List.
- Check the values by referring to the table below.COMBINATION METER:
Tester Display Measurement Item/Range Normal Condition Diagnostic Note Coolant Temperature Engine coolant temperature/Min.: 0°C (32°F), Max.: 127.5°C (261.5°F) After warming up: 80 to 100°C (176 to 212°F) - If -40°C (-40°F): Sensor circuit open
- If 140°C (284°F) or more: Sensor circuit shorted
OK
Engine coolant temperature value displayed on the tester is almost the same as needle indication.
NG → REPLACE COMBINATION METER ASSEMBLY
OK → GO TO SFI SYSTEM
