  • Engine coolant temperature sensor circuit explained. The engine coolant temperature sensor is a variable resistor known as a thermistor. The PCM runs multiple tests on the sensor circuit to check for shorts and opens. I refer to a wiring diagram to create both faults while monitoring the sensor signal with a voltmeter and a scantool.

    Great video please keep them coming. Old school technician . Can you do some on pull up and pull down circuits and the difference in ground side switched and positive side switch. Little lost. Thanks

    Very good job! Why doesn't the resistor inside the PCM create a voltage drop? Why, after that resistance, is the voltage still 5 volts?

      When it is unplugged, the circuit is incomplete, and voltage is not used.
