Engine Coolant Temperature Receiver Gauge Malfunction: Procedure

1. Check if CAN communication DTC is output. Refer to DIAGNOSIS SYSTEM .

   Result

   Result	Proceed to
   CAN communication DTC is not output.	A
   CAN communication DTC is output.	B

B → See step   6 

A: Go to next step 

1. Connect Techstream to the DLC3.
2. Ignition switch on (IG).
3. Turn the tester on.
4. Enter the following menus: Body Electrical / Combination Meter / Active Test.
5. 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 → See step   7 

OK: Go to next step 

1. Connect Techstream to the DLC3.
2. Ignition switch on (IG).
3. Turn the tester on.
4. Enter the following menus: Body Electrical / Combination Meter / Data List.
   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 95°C (176 to 203°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 → See step   7 

OK: Go to next step 

1. Connect Techstream to the DLC3.
2. Ignition switch on (IG).
3. Turn the tester on.
4. Enter the following menus: Powertrain / Engine and ECT / Data List.
5. Check the values by referring to the values in the table below.
   ENGINE AND ECT:
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   Coolant Temp	Engine coolant temperature/Min.: -40°C (-40°F), Max.: 140°C (284°F)	After warming up: 80 to 100°C (176 to 212°F)	-

   OK

   Engine coolant temperature value displayed on the tester is almost the same as actual engine coolant temperature.

   Result

   Result	Proceed to
   OK	A
   NG (for 2GR-FE)	B
   NG (for 1AR-FE)	C

B → See step   8 

C → See step   9 

OK: Go to next step 

1. Replace the combination meter assembly with a new or a normal one. Refer to REMOVAL - Step 3 .

   OK

   The operation of the combination meter assembly returns to normal.

   Result	Proceed to
   OK	A
   NG (for 2GR-FE)	B
   NG (for 1AR-FE)	C

B → See step   8 

C → See step   9 

OK → END
