Where is the ECT sensor located?
cylinder head
The ECT sensor is located in the left of the cylinder head and is connected to the Engine Coolant Temperature Sensor. Underneath the air intake pipe and behind the right cylinder head is where the Engine Coolant Temperature Sensor is located.
What happens when a ECT sensor goes bad?
If the coolant temperature sensor goes bad it can send a false signal to the computer and throw off the fuel and timing calculations. It is not uncommon for the coolant temperature sensor to fail and send a permanently cold signal to the computer. This will reduce fuel economy, and may hinder engine performance.
How can you tell if the ECT sensor is bad?
To confirm, you could run your vehicle through an emissions test. If everything else is in order, failure in this test should be because of a faulty coolant temperature sensor. Another telltale sign of your coolant temperature sensor not functioning properly is if your engine is overheating frequently.
How do you replace an ECT sensor?
Let’s Get Started
- Release the Cooling System Pressure. Locate and slowly remove the cooling system pressure cap to relieve the system of any residual pressure.
- Locate the Coolant Sensor.
- Remove the Electrical Connector.
- Remove the Coolant Sensor.
- Install the New Coolant Temperature Sensor.
- Refill the Cooling System.
How do I test my ECT sensor?
Ohmmeter-Testing Start with a cold engine. With the ignition off, disconnect the wiring connector from the (ECT) sensor. Attach an ohmmeter across the sensor’s terminals. Measure the sensor’s resistance and record the reading.
Can you drive with a bad ECT sensor?
It is possible to drive a vehicle with a faulty coolant temperature sensor as the management system defaults to a static reading. A vehicle’s coolant sensor is a critical component used by the engine management system. It directly affects, cooling and fueling of the engine and therefore affects how the engine performs.
Can bad ECT sensor cause misfire?
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. A bad one can easily cause a misfire or poor engine performance.
Do I have to drain coolant to replace ECT sensor?
Open the radiator valve and drain about, two to three quarts of coolant. You only need to remove enough, to drop the level below the sensor. This will minimize coolant waste, when you remove the sensor.
What is the function of ECT sensor?
A coolant temperature sensor (CTS) (also known as an ECT sensor or ECTS (engine coolant temperature sensor) is used to measure the temperature of the coolant/antifreeze mix in the cooling system, giving an indication of how much heat the engine is giving off.
