Check Engine Coolant Temperature Sensor
ENGINE COOLANT TEMPERATURE SENSOR
| Step | Check | Yes | No |
|---|---|---|---|
| 1 CHECK ENGINE COOLANT TEMPERATURE SENSOR. Check engine coolant temperature sensor. BASIC DIAGNOSTIC PROCEDURE . > or < Ref. to BASIC DIAGNOSTIC PROCEDURE . > |
Is engine coolant temperature sensor OK? | Go to step 2. | Replace engine coolant temperature sensor. |
2 CHECK HARNESS BETWEEN ENGINE COOLANT TEMPERATURE SENSOR AND COMBINATION METER.
Connector & terminal Normal meter: (E8) No. 3 - 012) No. 8: |
Is the measured value less than 10 ohm? | Go to step 3. | Repair wiring harness. |
| 3 CHECK WATER TEMPERATURE GAUGE GROUND CIRCUIT. Measure resistance between combination meter harness connector terminal and chassis ground. Connector & terminal (i12) No. 9 - Chassis ground: |
Is the measured value less than 10 ohm? | Check water temperature gauge. < Ref. To , REMOVAL , Water Temperature Gauge. > | Repair wiring harness. |
