How does the ECT temperature sensor work on a car?
How does the ECT temperature sensor work on a car?
The engine coolant (ECT) temperature sensor has two wires. One receives 5 Volts from the PCM. The other supplies a Ground path (inside the PCM too) for those 5 Volts. These 5 Volts are referred to as the 5 Volt Reference signal in all of the service and repair literature. The sensor’s resistance is higher the colder the coolant is.
Where is the coolant temperature sensor located in the engine?
Typically, the coolant temperature sensor is mounted in the engine block or cylinder head, near the thermostat or where the coolant flow is hottest. More than one coolant temperature sensor may be used on some systems to determine the temperature in different locations.
What’s the difference between CHT and ECT sensor?
Here are some specific differences between both of them: The engine coolant temp (ECT) sensor measures the temperature of the coolant, the cylinder head temperature (CHT) sensor measures the temperature of the metal itself (of the cylinder head) and no coolant is involved.
What happens if your coolant temperature sensor goes bad?
Fuel delivery, ignition timing and engine performance are among the key elements affected by the information the coolant temperature sensor gathers. If it goes bad, it can cause several problems. Signs Your Engine Coolant Temperature (ECT) Sensor Is Bad

Where does the coolant temperature ( ECT ) sensor go?
The readings from the engine coolant temperature (ECT) sensor; are sent back to the engine control unit (ECU). The engine coolant temperature (ECT) sensor is one of the most important; engine management sensors.
How does an engine coolant sensor work on a car?
This way, the computer knows how hot the engine is running and if it’s getting close to overheating. The ECT sensor may also control the temperature gauge on your dash, though in some vehicles, that is done instead by the engine coolant sending unit, otherwise known as a temperature switch.
