Where is the coolant temperature 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.

How hard is it to change a coolant temperature sensor?

The actual process of replacing the coolant temperature sensor is extremely simple. However, the difficult work comes in the preparation of the cooling system – both before and after. Tip: This job should only be completed when the engine is cold and has not been running for a minimum of one hour.

What happens when coolant temperature 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 coolant 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.

Can I drive my car with a bad coolant temperature sensor?

Does the coolant temp sensor control the fan?

The sensor works by measuring the temperature that’s being given off by the thermostat and/or the coolant itself. The temperature is then sent to the on-board control system. As the control system receives the temperature from the CTS, it may trigger the cooling fan to either shut off or turn on.
