Which is the engine temperature control module?
Which is the engine temperature control module?
When the temperature of the coolant reaches between 75 and 95 degrees (depending on the manufacturer specifications), the ECM instructs the radiator fan to turn on and start cooling down the liquid. Usually it is located either on the bottom of the radiator, or by follow the top radiator hose towards the engine block.
Where is the coolant temperature sensor located on an engine?
The readings produced from the coolant temperature sensor are transmitted to the engine control unit, where they are utilized as data for regulating and maintaining the proper ignition time and the optimal fuel injection through the computerized approach. The engine coolant temperature sensor is usually located on the engine block or cylinder head.
Where is the outside air temperature sensor located?
The outside air temperature sensor is normally mounted behind the grille or at the base of the windshield. Majority of these sensors work just the same as the engine air temperature sensor. However, some use an infrared sensor to check the body temperature of the vehicle’s occupants.
How does the cylinder head temperature sensor work?
Some cars use a cylinder head temperature or CHT sensor instead of, or in addition to the ECT sensor. The CHT sensor (see the photo) works the same way, but it measures the temperature of the cylinder head metal and is not immersed in coolant. This allows the CHT sensor to measure the temperature of the engine correctly even with loss of coolant.
How does the intake air temperature sensor work?
The intake air temperature sensor (IAT) tells the ECM the temperature of the air that is going into the engine. The cooler the air, the better the performance of the engine, which is probably why you might have noticed a difference in the car’s performance on a summer night as compared to the day.
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 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 is the engine control module located on a car?
Usually it is located either on the bottom of the radiator, or by follow the top radiator hose towards the engine block. You’ll see it on mounted on the engine block. It can be cleaned using a wire brush when you entirely change your engine coolant (approx. every 80,000 km or 50,000 miles).
