1.Disconnect the engine coolant temperature sensor connector. 2.Measure the resistance between connector terminals. Standard value:
|
|
Engine coolant temperature °C
|
Resistance kΩ
|
-20
|
22.4 - 29.4
|
0
|
7.35 - 9.25
|
20
|
2.74 - 3.32
|
40
|
1.14 - 1.34
|
60
|
0.52 - 0.60
|
80
|
0.26 - 0.29
|
100
|
0.14 - 0.15
|
|
3.If the resistance deviates from the standard value greatly, replace the sensor.
