Can you drive on a faulty coolant sensor?

Can you drive on a faulty 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.

How do I know if my cylinder head temperature sensor is bad?

Signs that indicate you need a cylinder head temperature sensor replacement include:

  1. You have trouble accelerating while driving your vehicle.
  2. The engine stalls when you start it cold.
  3. The idle speed stays low when the engine is cold.
  4. There is a long cranking time when you start your vehicle.

Is there a sensor for coolant?

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.

How long does a coolant temperature sensor last?

about 100,000 miles
Often, the engine coolant temperature sensor must be replaced at about 100,000 miles. If you don’t properly maintain the engine cooling system, the sensor could fail much earlier.

What should the temp of the coolant sensor be?

Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm. Get a wiring diagram and find out what ohms you should have at a specific temperature to check the function.

Why does my car coolant sensor keep dropping?

If there is a leak in the engine bay and the oil enters the engine block, the coolant will get contaminated, causing a problem to the ECT sensor. The coolant system of the car does not need constant refilling. However, if the coolant level is dropping frequently, there might be a leak which should be fixed immediately.

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.
