What is the rating of the coolant temperature sensor?

Average rating from 17,525 customers who received a Change Oil and Filter. The coolant temperature sensor, also known as the coolant temperature switch, is an engine management system sensor that is used to monitor the temperature of the engine’s coolant.

Where is coolant temp sensor on GM 3800?

Coolant Temp sensor (ECT) 9. Evap Purge Solenoid Typical engine data sensor and control component locations on the GM 3.8L 3800 v6 engine. Exact location may vary depending on vehicle year / make / model. Click on a number for a description of the component. A few related auto repair questions and answers.

Why is my coolant temperature sensor not working?

If you were to test the coolant temperature sensor alone, you may think that it failed because its resistance value has remained at about 1500 or 2100 ohms, for example, when in fact the sensor is reporting the coolant actual temperature and it’s working properly. You could relay on the temperature gauge on your dashboard.

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.

Where is the coolant temperature sensor located in the engine?

Typically, the coolant temperature sensor is mounted in the engine block or cylinder head, near the thermostat or where the coolant flow is hottest. More than one coolant temperature sensor may be used on some systems to determine the temperature in different locations.

What happens if your car coolant sensor is not correct?

Your engine is overheating: If the engine’s computer doesn’t receive the correct temperature reading, it may not slow the ignition timing and turn on the cooling fans when necessary, causing the engine to overheat. If this happens, pull off the road and shut the car off as quickly as possible, as overheating can quickly kill your engine.

Where is the data sensor on a GM 3.8L 3800 V6?

Typical engine data sensor and control component locations on the GM 3.8L 3800 v6 engine. Exact location may vary depending on vehicle year / make / model. Click on numbers below image for component information.

How much does it cost to replace a coolant temperature sensor?

Unscrew the ECT sensor in an anticlockwise direction, similar to how a spark plug is removed. Install the new sensor and reconnect the connector cable. The average replacement cost of the Coolant Temperature Sensor is between $100 and $220. The labour cost is between $40 and $140 while the part itself costs between $50 and $80.

What does an engine coolant temperature switch do?

Also sometimes referred to as an engine coolant temperature (ECT) sensor or coolant temperature switch, sensors help keep your engine operating smoothly at the right temperature. Temperature sensors are thermistors, resistors whose resistance changes with temperature.

What does the coolant temperature sensor do on an engine?

The engine coolant temperature sensor’s job is to measure the coolant temperature for the engine control module. With this information, the engine control module adjusts the air-fuel mixture depending on the temperature. This article will discuss the most common symptoms of a bad coolant temperature sensor, location, replacement cost,

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.

What should coolant temp be when engine is hot?

With a good OBD2 code reader, you can also check the live data and the parameters of the CTS sensor. 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.

What to do if your coolant sensor is not working?

So, if the sensor doesn’t work properly, your temperature gauge won’t be of much help either. By using the thermometer, it won’t take you long to figure out that the thermostat isn’t working. You’ll notice the engine’s temperature is not rising above 85 or 90 degrees, for example.

How does a coolant sensor work on an engine?

Most coolant temperature sensors operate using electrical resistance to measure the temperature of the coolant. This signal is then sent to the computer so that changes can be made to the engine’s timing and fuel calculations for optimal performance, as engines require more fuel when they are cold, and less fuel when they are fully warmed up.

Where is the coolant temperature sensor on a Honda Accord?

The coolant temperature sensor in all three engines distributed the coolant temperature to other electronic controls and the temperature gauge. Honda tucked the sensor out of site, so finding it can be a little tough.

What are the symptoms of a bad coolant temperature sensor?

Hence, it is advised to have your car inspected right away to avoid any serious problems. Here is a more detailed list of the common symptoms of a bad coolant temperature sensor. One of the first symptoms you will notice is that the check engine light will activate.

How much does a coolant temperature sensor cost?

$92.73 – $160.32. Price range for all vehicles. Average rating from 17,525 customers who received a Change Oil and Filter. The coolant temperature sensor, also known as the coolant temperature switch, is an engine management system sensor that is used to monitor the temperature of the engine’s coolant.

How does an engine coolant sensor work on a car?

This way, the computer knows how hot the engine is running and if it’s getting close to overheating. The ECT sensor may also control the temperature gauge on your dash, though in some vehicles, that is done instead by the engine coolant sending unit, otherwise known as a temperature switch.

Where is the coolant level sensor on the radiator?

Some manufacturers use more complicated sensor designs, but the result is the same: if the coolant drops below its proper level, the warning light comes on. The coolant sensor can be located either on the radiator (toward the top of one of the reservoir tanks) or at the bottom of the expansion tank.
