WARNING: This page is about a different variant/trim than selected.
- READ VALUE USING TECHSTREAM (CHECK FOR OPEN IN WIRE HARNESS)
*1 No. 2 Engine Coolant Temperature Sensor *2 ECM *a Front view of wire harness connector
(to No. 2 Engine Coolant Temperature Sensor)- - - Disconnect the No. 2 engine coolant temperature sensor connector.
- Connect terminals 1 and 2 of the No. 2 engine coolant temperature sensor connector on the wire harness side.
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Enter the following menus: Powertrain / Engine / Data List / Radiator Coolant Temperature.
Powertrain > Engine > Data List
Tester Display Radiator Coolant Temperature - According to the display on the Techstream, read the Data List.
OK
Techstream Display Specified Condition Radiator Coolant Temperature Higher than 135°C (275°F) Result
Proceed to OK NG
Result:
OK
REPLACE NO. 2 ENGINE COOLANT TEMPERATURE SENSOR. Refer to REMOVAL [02/2019 - 08/2020]
