Where is the ECT sensor located?
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?
One of the first symptoms associated with a problem with the coolant temperature sensor is poor fuel economy. If the coolant temperature sensor goes bad it can send a false signal to the computer and throw off the fuel and timing calculations. 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 vehicles coolant sensor is a critical component used by the engine management system. It directly effects, cooling and fueling of the engine and therefore effects how the engine performs.
How do you change 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.
What does a faulty temp sensor do?
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. When this happens, the car might misfire, or it could lead to engine knocking.
What happens if you drive with a bad coolant temperature sensor?
Faulty readings from the coolant temperature sensor can cause your car’s engine to miscalculate the fuel to air mixture within the engine. If the amount of black smoke emitting from your car is excessive, then you should not drive your car and you should tow your vehicle to a mechanic.
