How many volts does the ECT sensor use?
How many volts does the ECT sensor use?
ECT (Engine Coolant Temperature) Sensor. The ECT sensor is usually a two wire sensor that uses a 5 volt reference from the PCM with a ground signal back to the PCM. In general terms if the ECT reading is cold the reading could be less than 0.5 volts (on the ground signal) and when the engine is hot the reading could be around 4 volts.
What does ECT stand for in an engine?
ECT (Engine Coolant Temperature Sensor. An ECT sensor, or Engine Coolant Temperature Sensor is a sensor that is screwed into the engine’s block or cylinder head and is used to determine the temperature of the engine coolant.
What kind of circuit is the ECT circuit?
The ECT circuit is a variable ground, which uses a voltage divider network (Figure 1) where the voltage is divided between the sensor input and a sensor ground inside the computer (Black Box).
What should the ECT reading be on my car?
ECT (Engine Coolant Temperature) Sensor. In general terms if the ECT reading is cold the reading could be less than 0.5 volts (on the ground signal) and when the engine is hot the reading could be around 4 volts. For specific readings for your application, see a vehicle-specific repair manual.
What should the voltage be on the ECT?
Connect the positive wire of the voltmeter is to the ECT signal terminal. Start the engine form cold state. Depending on the temperature, voltage readings should be in the range of 2V to 3V. The relationship between the voltage and the temperature is shown in Table-1.

How is the pressure of a battery measured in ECT?
The “pressure” produced by the battery is its voltage, measured in volts [a unit of electrical force]. The higher the voltage, the more current will flow. The voltage is the cause, and the current is the effect. In ECT, a voltage is applied to two electrodes placed on the patient’s head.
