  Q: How to check and replace the Coolant Temperature Sensor for the Honda Passport?

  A: To check the coolant temperature gauge, see if the fuses are blown. In case the needle reads "hot" with a cold engine, take off the wire going to the coolant temperature sender. If it falls, replace the sender unit. Otherwise, there is something wrong with either the wire or gauge itself. Different models of engines have different places where senders are fixed. Again, if the engine has warmed up and the gauge does not respond, ground that wire to test it further. Replace this sender if "Hot" is shown by the instrument cluster. In case it does not indicate overheating; an open circuit may be present or a defective gauge can be observed. Check resistance of this sender by heating it in water. Replace this item when necessary.

  Q: What is the Engine Coolant Temperature (ECT) Sensor on Honda Passport?

  A: The Engine Coolant Temperature (ECT) Sensor is a thermistor located in various places depending on the engine type. Check the resistance value of the sensor when cold and when warm, and compare to the values specified in the accompanying chart. If the resistance values are correct, check the reference voltage to the sensor from the PCM. Before installing the new sensor, wrap the threads with Teflon sealing tape, disconnect the electrical connector, handle it with care, install it securely, and check the coolant level.
