4. ENGINE COOLANT TEMPERATURE SENSOR
NOTE: Allow the engine to cool to ambient temperature before proceeding.
WARNING: Make sure the engine cooling system is cool before removing the pressure cap or any hose. The cooling system is pressurized when
hot. Failure to follow these instructions can result in possible serious or fatal injury.
1. With the scan tool, read the Engine Coolant Temperature Sensor value for each sensor. If the engine was allowed to cool completely, the value
should be approximately equal to the ambient temperature.
2. Monitor each sensor value on the scan tool and the actual coolant temperature with a thermometer.
3. Start the engine.
WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not
wear loose clothing. Failure to follow these instructions may result in possible serious or fatal injury.
NOTE: The sensor value transition should be smooth as the engine reaches operating temperature. The thermometer reading and the coolant
temperature values on the scan tool should remain relatively close.

5. ECT SIGNAL CIRCUIT HIGH RESISTANCE
NOTE: Perform this procedure for the sensor where erratic sensor values were detected in the previous test step.
1. Turn the ignition off.
NOTE: When checking circuits at the Powertrain Control Module (PCM), be careful not to damage or distort the connector terminals.
Improper measurement technique could result in poor pin to terminal contact.
2. Using a voltmeter, perform a voltage drop test by backprobing the ECT Signal circuit at the Engine Coolant Temperature Sensor harness
connector and at the PCM. Make sure the voltmeter leads are connected so that positive polarity is displayed on the voltmeter.
WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not
wear loose clothing. Failure to follow these instructions may result in possible serious or fatal injury.
3. Start the engine.
