17 INSPECT ENGINE COOLANT TEMPERATURE SENSOR
(a) Remove the engine coolant temperature sensor.
(b) Measure the resistance between the terminals.
Standard:
2.32 to 2.59 kat 20_C (68_F)
0.310 to 0.326 kat 80_C(176_F)
NOTICE:
If you check the engine coolant temperature sensor in wa-
ter, be careful not to allow water to contact the terminals.
After checking, dry the sensor.
HINT:
Alternate procedure: Connect an ohmmeter to the installed en-
gine coolant temperature sensor and read the resistance. Use
an infrared thermometer to measure the engine temperature in
the immediate vicinity of the sensor. Compare these values to
the resistance/temperature graph. Change the engine temper-
ature (warm up or allow to cool down) and repeat the test.
(c) Reinstall the engine coolant temperature sensor.
