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.
What is a coolant 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.
How much is a coolant sensor?
The average price for an engine temperature sensor replacement is between $150 and $193. Labor costs are between $82 and $105 while parts are between $66 and $88.
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.
What happens when your coolant sensor goes bad?
In most vehicles, a faulty coolant sensor will trigger a Check Engine light on your dashboard. However, there are more symptoms you should be aware of. If your engine is frequently overheating or using more gas than usual, it‘s time to check on your coolant sensor. Black smoke from the exhaust pipe may also point to failure in this sensor.
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.
