Coolant temperature sensor location manual

Where is the Coolant Temperature Sensor located? The coolant temperature sensor will be located directly behind the coolant pipe. In most modern cars and vehicles, this is present behind the right cylinder head that is located right underneath the air intake pipe.

How many coolant temperature sensors are there?

There are two temperature sensors in some vehicles, one to send information from the engine system to the control unit and another from the control unit to the dashboard.

What happens if I unplug coolant temperature sensor?

What Happens If You Unplug The Coolant Temp Sensor? What is this? Unplugging the engine coolant sensor while the car is running will likely cause the engine to stumble and run rough. The engine light may not come on imminently, but a DTC (Diagnostic Trouble Code) will be logged in the PCM.

Does the coolant temperature sensor control the thermostat?

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.

How do you know if your coolant sensor is bad?

Symptoms of a Bad Coolant Temperature Sensor If your vehicle starts to use a lot more gasoline than usual, or black smoke is starting to come from the exhaust pipe, these are indicators that the coolant temperature sensor in your vehicle could be defective, and needs to be replaced.

How do I know if my coolant temperature sensor is bad?

What Signs May Signal Your Coolant Temperature Sensor May Be Failing?

Poor Fuel Economy.
Irregular Temperature Readings. ...
Black Smoke from Your Exhaust. ...
Your Engine is Overheating. ...
Your Check Engine Light is On.

Is coolant sensor and temperature sensor the same?

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.

Can you change coolant temperature sensor?

Using a wrench, unscrew the coolant temperature sensor from the coolant passage. A ratcheting wrench can be a big time saver in tight spaces. Insert the new sensor. Torque to spec listed in your repair manual, usually under 20 lb-ft.

Can you change temperature sensor without draining coolant?

Do you need to drain coolant to change coolant temperature sensor? Open the radiator valve and drain about two to three quarts of coolant. You only need to remove enough to drop the level below the sensor.

What will a bad temp sensor do?

If you notice that your engine overheats, the coolant temperature sensor could be the problem. At times, the coolant temperature switch may fail such that it starts transmitting hot signals permanently. This causes the computer to erroneously counterbalance the signal, thereby causing the engine to misfire or overheat.

Can you reset a temperature sensor?

Reset Or Replace The Sensor You can replace or reset ambient air temperature sensor after removing it. You have to replace it if there is sensor malfunctioning. Or find the reset button on it. There are Mode buttons on the sensor in some cars that allow you to do so.

Can you drive with faulty coolant sensor?

We would not advise you to drive with a faulty engine coolant temperature sensor. Running your car rich can lead to excess carbon buildup, which leads to its own set of serious issues. The sensor is inexpensive and quick to replace compared to any engine damage that its failure can cause.

Does coolant temp sensor affect idle?

Can a bad coolant temp sensor cause rough idle? Yes, due to the false signal sent to the car computer, it will adjust the air-fuel mixture. The supplied mixture will not be enough and result in vibrations and shaking at idle or low-speed maneuvers and lead to other strange behavior and loss of engine power.

Is temperature sensor and thermostat same?

Temperature Sensors provide an analogue output, the description of a device with a digital output is known as a Thermostat.

What controls the coolant sensor?

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.

How do I test my coolant sensor?

Gently lower the end of the sensor into the water until the entire device is fully submerged. Wait a minute or so for the screen to give you a reading of the cold water. Once you have a reading, write down the measurement for reference. A common reading for a temperature sensor in cold water is around 5 volts.

Can a coolant sensor be cleaned?

In most cases, there is little to clean and reuse as when a sensor goes out of calibration from wear or mechanical damage, or fails due to heat damage, the only repair is to replace them.

How long does it take to change a coolant temperature sensor?

If you are doing it yourself it will take 4 to 5 hours. However if a skilled mechanic is doing it, it will take 2 to 3 hours only. Whether your car was running or not. If the engine of your car is running, then you will have to wait at least 1 hour before you start replacing the bad coolant temp sensor.

How often should a coolant temperature sensor be replaced?

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.
