What is the ECT sensor in an engine?
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. The ECT sensor is basically a thermistor that changes resistance with temperature.
What happens to the resistence of the ECT sensor?
The ECT sensor is basically a thermistor that changes resistance with temperature. When the ECT (engine coolant temperature) is high (hotter), the resistence is low, and when the ECT is low (cooler) the resistence is high. This resistance reading is sent to the vehicle’s PCM/ECM (car’s onboard computer)…
Is the ECT sensor the same as the coolant temperature sender?
Note that the ECT sensor is not the same thing as a coolant temperature SENDER. The temperature sender is typically used as the reading for the temperature gauge on the instrument cluster. Here is a photo of one ECT sensor:
When to replace an engine coolant temperature sensor?
Consequently, engine coolant temperature sensor (ECT) replacement usually happens only after they have failed. While, its function is vital, all it really does is; keep track of the changing temperatures of your engine coolant. First, the vehicle’s (PCM/ECM) sends a 5 volt reference signal to the engine coolant temperature sensor (ECT).
How can I replace the ECT sensor on my car?
So now you’re ready to replace the ECT sensor. 1. Park your car in a safe place where you can work comfortably and let the engine cool. 2. Place a clean drain pan under the radiator, open the radiator valve and drain about two to three quarts of coolant (or just enough to drop the level below the sensor). Then close the drain valve.

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.
How much does it cost to replace a CTS sensor?
Replacing the CTS yourself can save you about $150 in repairs or more, depending on your particular vehicle model. And the best part is that, for most models, the sensor is readily accessible, so the average car owner can perform this repair at home using common tools. All you need is one or two hours of work in your garage on a Saturday morning.
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 happens if the ECT sensor gets damaged?
Like every other component, the ECT sensor can also get damaged resulting in a number of engine-related problems. Hence, it is advised to have your car inspected right away to avoid any serious problem. Here are some of the common symptoms you might face if the ECT gets damaged or becomes faulty.
When does the coolant temperature sensor need to be replaced?
Noted below are a few of the warning signs that will alert you that the coolant temperature sensor is damaged and needs to be replaced. The engine is getting poor fuel economy: when the coolant temperature sensor is not functioning correctly, it tends to relay false information to the engine control module.
Can a car have more than one coolant sensor?
Some vehicles may have more than one temperature sensors, as sometimes different sensors are used to send the signals to the dashboard and the control unit of your engine system. This is optional and a manufacturer can use only one coolant temperature sensor to send the signals to both of these desired receivers.
Where is the ECT sensor on a Honda Civic?
Your Honda Civic’s engine coolant temperature (ECT) sensor is located in the front right section of your engine block.
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.
What does it mean if your ECT sensor is bad?
If your car does have some trouble starting, specifically after the engine has warmed up to operating temperatures, this may also indicate that the ECT sensor is faulty. In addition, if you have to pump the gas pedal when cold-starting your car to keep it from dying, this may be another indication that your ECT sensor has gone bad.
Your Honda Civic’s engine coolant temperature (ECT) sensor is located in the front right section of your engine block.
How does the coolant temperature ( ECT ) sensor work?
The engine control module (ECM) uses this sensor to constantly measure the engine’s temperature. It is then able to regulate the fuel levels and idling, so it can adjust the spark as well as the exhaust gas regulation (EGR) valve functions.
What happens if your ECM is not correct?
If the ECM of your car is not receiving the correct temperature reading, it may adjust other components of the engine. This causes them to run under abnormal settings, and causes a change in fuel mixture or even a complication within the engine block.
Where are the ECT/EOT sensors located?
Your ECT sensor (03 model) is just to the left of the thermostat housing on the front cover (looking at the engine from the front of the truck). The EOT sensor is on the oil filter base . If you can find where the coolant hose for the egr cooler connects on that cover, the sensor is closer to the oil filter housing than that hose connector.
Were is the ECT sensor?
In most vehicles, the main ECT sensor is called the primary ECT sensor, or ECT sensor one. This is installed near the thermostat within the cylinder head or block . The cylinder head sits above the cylinders on top of the cylinder block in an internal combustion engine.
Where is engine coolant sensor located?
The Engine Coolant Temperature (ECT) Sensor is located on the left side of the engine. It is mounted in the cylinder head next to the oil indicator stick.
Where is the fuel temp sensor located?
The Fuel Temperature Sensor is located on the fuel rail under the upper intake manifold shield. It will have a two wire connector going to it.
