How does the ECT sensor work in a car?
How does the ECT sensor work in a car?
The engine coolant temperature sensor, also known as the ECT sensor, is a negative temperature coefficient thermistor – meaning, the electrical resistance goes down, while the temperature rises. When a signal from the ECT sensor is missing or it is outside of the expected range, the powertrain control module turns on the check engine light.
What does temperature sensor do on Ford F-150?
The sensor also sends the temperature of the water/antifreeze mixture to the computer, so that the computer can make adjustments in timing, air and fuel mixture, and other adjustments needed by the truck to run ai its optimum performance levels and get the best fuel mileage.
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.
Why does my ECT sensor always read hot May?
So, a faulty (ECT) sensor that always reads cold may; cause the fuel control system to run rich pollute and waste fuel. Also, a (ECT) sensor that always reads hot may; cause cold driveability problems such as stalling, hesitation and rough idle.

What happens if your ECT sensor is bad?
Once the car is warm, it switches to relying on the oxygen sensors for a more precise reading. A failed ECT sensor can prevent this change from happening, resulting in a rich-running engine and poor fuel economy. 4. Your engine runs poorly: The sensor affects almost every aspect of engine management.
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.
