INSPECTION

Remove the ECT sensor

Suspend the ECT sensor [1] in a pan of coolant on

an electric heating element and measure the

resistance through the sensor as the coolant heats

up.

• Soak the ECT sensor in coolant up to its

threads with at least 40 mm (1.6 in) from the

bottom of the pan to the bottom of the sensor.

• Keep the temperature constant for 3 minutes

before testing. A sudden change of

temperature will result in incorrect readings.

Do not let the thermometer or ECT sensor

touch the pan.

Measure the resistance between the ECT sensor

terminals.

Temperature

40°C (104°F) 100°C (212°F)

Resistance

1.0 – 1.3 kΩ

0.14 – 0.17 kΩ

Replace the ECT sensor if it is out of specification.
