Where Is The Coolant Sensor Located?

Usually, the location of 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 of the air intake pipe.Feb 1, 2021

What happens when the coolant temperature sensor goes bad?

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. … This will reduce fuel economy, and may hinder engine performance.

How do you know if your coolant temp sensor is bad?

Bad coolant temp sensor symptoms are a change in the car’s mileage, an illuminating check engine, a cloud of black smoke coming from the exhaust pipe, and warnings of engine overheating. Your vehicle’s engine must stay within a specific temperature range to perform properly.

Can you drive a car with a bad coolant temperature sensor?

It is possible to drive a vehicle with a faulty coolant temperature sensor as the management system defaults to a static reading. A vehicle’s coolant sensor is a critical component used by the engine management system. It directly affects, cooling and fueling of the engine and therefore affects how the engine performs.

How much does it cost to replace a coolant temperature 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.

Does the coolant temp sensor control the fan?

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. … As the control system receives the temperature from the CTS, it may trigger the cooling fan to either shut off or turn on.

Can a coolant temp sensor keep a car from starting?

The sensor will not cause a no start. It could cause a hard start and a rich or lean condition only.

How many coolant temperature sensors are in a car?

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. The device follows the principle of dependence of potential difference in temperature.

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. Then close the drain valve. This will minimize coolant waste when you remove the sensor.

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

The actual process of replacing the coolant temperature sensor is extremely simple. However, the difficult work comes in the preparation of the cooling system – both before and after. Tip: This job should only be completed when the engine is cold and has not been running for a minimum of one hour.

What causes coolant temperature sensor failure?

One of the common problems is; when the sensor has a, poor connection inside or in the connector. This causes interruptions in the signal to the (PCM) and the (PCM) sets the fault. In some vehicles, symptoms of this problem show up as, erratic readings of the temperature gauge.

Can you clean a coolant temperature sensor?

In most cases, sensors for your automobile will need to be replaced if they fail, but depending on the type of sensor and its location or function, some can be cleaned and reused. Sensors can come in many types and are used for a variety of systems on modern cars.

Why does my low coolant light came on when its full?

Your coolant light will come on when the sensor senses an incorrect change in the temperature in your system. Typically the sensor, which monitors the coolant temperature, knows how to adjust to varying temperatures depending up the status of your car; running, warming up, or cold.

What does a coolant temperature sensor do on a car?

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 do you test a cooling sensor?

The coolant temperature sensor is located on the engine block under the hood. Pull the latch for the hood and open it, making sure it is secure before letting go. You will search for the sensor within the engine block itself, using a drop light if you need help to see it better.

What sensor turns on the radiator fan?

coolant temperature sensor
On most modern cars, the cooling fan is controlled by the Engine Control Unit (ECU) which gets a signal from the coolant temperature sensor. If it’s not working, the fan won’t turn on when it needs to, which means the engine might overheat.

How do you change a coolant temperature sensor?

Does coolant temp sensor affect AC?

The cooling of the air conditioner should not be affected by the engine cooling temperature.

What sensor would stop a car from starting?

The most common sensors that will stop your car from starting include the camshaft sensor, the crankshaft sensor, the mass air flow (MAF) sensor, the manifold absolute pressure (MAP) sensor and the throttle position sensor.

Can a bad temp sensor cause stalling?

The signal from the coolant temperature sensor tells the engine’s computer when to apply extra gasoline during a cold start. A faulty sensor can confuse the computer, keeping it from providing enough fuel. As a result, the engine may hesitate or stall.

Can no coolant cause no start?

Having no coolant in your engine can kill it very effectively if driven like that for any substantial amount of time and in many of the newer models of vehicles, it will tell your car not to start until it full of coolant, to prevent break down.

What are the signs that the sensors are failing?

An Engine That Sounds Rough

If your vehicle has a bad oxygen sensor, it could run irregularly or sound rough when it idles. A faulty oxygen sensor can impact your engine’s timing, combustion intervals, and other essential functions. You could also notice stalling or slow acceleration.

Where is the temperature sensor on a thermostat?

The thermostat sensor is located near the evaporator coils. These coils are inside your air conditioner unit. As the air is sucked through the return vents, the air passes by the sensor and the coils. As the air passes the sensor, it reads the temperature and compares that reading to the setting on your thermostat.

How do I know if my temperature sensor is working?

Your Check Engine Light is On

Alongside the signal that your engine is overheating, you may see your check engine light come on if your coolant temperature sensor is failing or has failed. If your car’s computer senses a problem with the signal your sensor is sending, it may trigger the check engine light.

Where do you put a coolant temperature sensor?

The coolant temperature sensor is located on the front of the engine block. This will vary on some cars where the pulleys are located on the side of the vehicle. However, the sensor is still located amongst the pulley system. Hold a drop light over the area and locate the sensor.

What is thermostat sensor?

A thermostat is a contact type temperature sensor consisting of a bi-metallic strip made up of two dissimilar metals such as aluminium, copper, nickel, or tungsten. The difference in the coefficient of linear expansion of both the metals causes them to produce a mechanical bending movement when it’s subjected to heat.

What is diagnostic code P0128?

What the P0128 code means. The P0128 code means that the engine coolant is not getting warm enough, fast enough. In other words, there is a problem with the engine operating temperature not being reached within a certain amount of time.

How often do coolant temp sensors go bad?

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.
