How much does it cost to replace ECT sensor?
To replace the ECT sensor, you are going to pay, on average, $95-$140. How much you pay depends on the type of car you own and where you go for servicing. Each mechanic has their own rates, and they may be getting their parts from a variety of vendors, which can change how much the parts cost you.
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.
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.
How do you know if you have a bad ECT sensor?
If you notice more fluctuation in your engine temperature or it looks higher or lower than usual while you’re driving, it could be the engine coolant temperature sensor. In particular, if your engine doesn’t seem to be warming up as it typically does, you should have a mechanic take a look at your cooling system.
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.
Can a bad ECT cause no start?
If you have starting problems and the ‘check engine’ light doesn’t come on, you may have a bad engine coolant temperature sensor (ECT). They’re quick and easy to replace.
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.
Can a bad ECT sensor cause overheating?
Engine Overheating While sometimes a faulty sensor sends a permanent cold signal to the engine, it can also send a permanent hot signal. The computer will again miscalculate the signal and cause the engine to heat up instead of cooling it down.
