Engine Coolant Temperature (ECT) Sensor Inspection
1)
Remove ECT sensor referring to
Engine Coolant Temperature (ECT) Sensor Removal and Installation:K9K
.
2)
Immerse temperature sensing part of ECT sensor in water and measure resistance between sensor terminal (1) and (2) while heating water gradually.
If measured resistance doesn’t show such characteristic as shown, replace ECT sensor.
If measured resistance doesn’t show such characteristic as shown, replace ECT sensor.
ECT sensor resistance
| Water temperature °C (°F) | Resistance (kΩ) |
|---|---|
| 25 (77) | 2.140 – 2.364 |
| 50 (122) | 0.770 – 0.850 |
| 80 (176) | 0.272 – 0.288 |
