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.

Can a bad coolant sensor cause a car to not start?

Some cars use the engine coolant temperature sensor to control the electric cooling fans. You have two separate temperature sensors for the fans, dashboard gauge, and engine management in most cars. However, if your car has a single sensor, a bad engine coolant temperature sensor may result in your fans won’t start at all.

How does coolant temperature sensor affect engine performance?

A bad engine coolant temperature sensor affects engine performance: It may cause a constant lean air/fuel mixture, causing the engine to stall or idle rough. Or it may cause a constant rich air/fuel mixture, causing an increase in emissions and fuel consumption.

What does a bad coolant temperature sensor do?

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.

The coolant temp sensor (s) have a few jobs. They send a signal to the gauges so you can monitor engine temperature, they tell the radiator fans when to kick on or off, and they let the ECU know how warm the engine is so that it can fine-tune the fuel delivery to give you maximum performance as well as fuel efficiency.

What is the temperature of the coolant in an engine?

If your car model has two coolant temperature sensors, one is used by the temperature gauge, and one is used for the engine control unit. Engine temperature sensors are easy to measure with a multimeter, but you need to find the right values of them.

Why does my car have a coolant temperature sensor?

On older cars, you usually found a coolant temperature sensor, with two wires up directly to the cluster. This is because there was no engine control unit in the car that used the coolant temperature as information.

Why does the coolant temperature gauge stay on cold?

The most common causes of a coolant temperature gauge which stays on cold are with the coolant temperature sensor itself. It’s recommended to check this component first. If you have more questions about this topic, you are welcome to leave a comment below, and I will try to answer your questions as fast as possible.

How can I test my crankshaft position sensor?

The most accurate way to test a crankshaft position sensor is checking the sensor signal with an oscilloscope. Sometimes, the sensor may have an intermittent fault that is not present during testing. In this case checking for Technical Service Bulletins (TSBs) and researching common problems may help.

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 get what ohms you should have at a specific temperature to check the function.

Can a bad coolant sensor cause engine performance to drop?

The engine coolant temperature sensor can have a hard impact on the air-fuel mixture. A bad air-fuel mixture can also cause the engine performance to drop drastically. If you feel that the engine performance is not what it has been before, it may be due to a faulty engine coolant temperature sensor.

How much does it cost to replace coolant sensor?

If you are doing the job yourself the cost of the sensor will be between $14.00 and $24.00 (US). You will also need a gallon of coolant to refill the system once the job is complete. A video of this job being done is at the bottom of this guide.

How does the coolant sensor work in a car?

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. By the end of this post you’ll know how the sensor works, how to diagnose a faulty sensor, wiring and control module.

How much does it cost to replace a coolant sensor?

To illustrate, here are estimates of the coolant temperature sensor price on some common vehicles using a labor rate of $100 per hour: 2010 Ford Fusion 3.0-liter engine – it usually takes half an hour of labor to replace the sensors. A GDP replacement sensor is about $19 which makes a total job cost of about $69.

What happens if your coolant sensor goes bad?

Without the appropriate scan tools or diagnostic experience, symptoms of a failed coolant temperature sensor may lead you in the wrong direction. Rough running, poor acceleration, decreased fuel economy, and even overheating can result from a faulty temperature sensor.

Where can I find the coolant temperature sender?

Locate the Coolant Sensor There are usually only three places the coolant temperature sender can be located which is: In or near the thermostat housing, in the cylinder head or in the intake manifold. To find where the sensor is located check Google images or you can use an online service like Mitchell1.

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.

What to do if your coolant gauge is not working?

Temperature Gauge Not Working? How to Replace a Coolant Temperature Sensor. VW Golf. – YouTube If playback doesn’t begin shortly, try restarting your device. Videos you watch may be added to the TV’s watch history and influence TV recommendations. To avoid this, cancel and sign in to YouTube on your computer.

Why is the temperature gauge on the dashboard not working?

Thus, the temperature gauge on your dashboard is your window into the coolant temperature as seen by the temperature sending unit. It lets you know when the engine is cool, at operating temperature, overheating, or fluctuating. The sending unit is a thermistor. It is exposed on one side to engine coolant.

What does it mean when your coolant sensor says p0118?

A code P0118 may mean that one or more of the following has happened: An open in the ground circuit between the ECT sensor and the PCM A short in the voltage feed between the sensor and the PCM A bad temperature sensor (shorted internally) First, if you have access to a scan tool, check the reading of the coolant sensor.

What to do if your temperature sensor is out of specs?

If the scan tool reads an illogical temperature, check the resistance of the temperature sensor. If it is out of specs, replace it. If it is in specifications, unplug the sensor and, using a fused jumper wire, jumper the two terminals of the connector together. The temperature reading should now be maxed out to above 250 degrees F.

When does sensor resistance drop coolant temperature drops?

Sensor resistance is high when coolant temperature is low and resistance drops when coolant temperature increases. The powertrain control module (PCM) provides a 5 volt reference and a ground to the sensor.

Examine the wiring harness plug for the temp sensor. Use Mass Air Flow cleaner and a brush to clean the plug if there is any residue or corrosion. Plug the new coolant temp sensor into the wiring harness, and fit it back into the housing. Refit the u-shaped lock when the sensor is fully seated.
