When looking from the front of the car with the hood opened, the coolant temperature sensor is on the back of the front head which would be on the drivers side of the car.

Likewise, people ask, where is the temperature sensor coolant?

Start by having a look at the unit itself to check its condition, as sensors/gaskets/connectors can develop cracks with extended use and continual temperature cycling. The CTS is usually found at the front of the car, near the thermostat housing, or on the radiator.

Furthermore, can you drive with a bad coolant sensor? Anyone with specific knowledge weigh in. Usually the Coolant Temp Sensor is used for the gauge for fuel trims for cold start enrichment, and fan control. Since the Thermostat and water pump are mechanical the engine will still cool. you will be fine driving until the replace the sensor.

Similarly, you may ask, how do I know if my temperature sensor is bad?

Symptoms of a bad or failing coolant temperature switch (sensor)

  1. Poor fuel economy. One of the first symptoms associated with a problem with the coolant temperature sensor is poor fuel economy.
  2. Black smoke from engine. Another symptom of a possible problem with the coolant temperature sensor is black smoke from the vehicle's exhaust.
  3. Overheating engine.
  4. Check Engine Light comes on.

Where is the cooling fan sensor?

The cooling fan relay is normally located in either the underhood fuse and relay center or mounted to the electric fan assembly behind the radiator.

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

Signs Your Engine Coolant Temperature (ECT) Sensor Is Bad
  1. Your check engine light is on: If the engine's computer detects a problem with the coolant temperature sensor, or its circuit, it will turn on the check engine light.
  2. Your engine stalls: When the engine is first started, it will require more fuel in order to idle smoothly until it's warmed up.

What happens when a coolant temperature sensor goes bad?

One of the first symptoms associated with a problem with the coolant temperature sensor is poor fuel economy. If the coolant temperature sensor goes bad it can send a false signal to the computer and throw off the fuel and timing calculations. This will reduce fuel economy, and may hinder engine performance.

Where is the temperature sensor located in a car?

Generally, the outside temperature sensor is located under the front of the hood near the bottom of the car. Although the sensor itself is accurate, the location causes the sensor to pick up heat from the road surface.

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

If the sensor is reading too high of temperature when compared to the ambient air temperature sensor when first started then the computer would see it as a problem and turn on the check engine light an go into failure management mode and use a known good reading. The sensor will not cause a no start.

Does the coolant temperature 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.

Do you need to drain coolant to change coolant temperature sensor?

Locate and slowly remove the cooling system pressure cap to relieve the system of any residual pressure. You will then need to drain the cooling system because the sensor is submerged in coolant and when it is removed coolant will leak from the coolant port.

Should radiator fan run all time?

An electric fan SHOULD NOT run all the time. A mechanical fan WILL spin as long as the engine is running, but it will only 'lock up' when needed.

What is the difference between a coolant temperature sensor and sender?

But a SENDER can be anything that sends a signal such as a telegraph sender. A SENSOR detects something such as temperature, pressure, light, etc. and generates a signal (which can be sent).

What are the symptoms of a bad IAT sensor?

Symptoms of a Bad IAT Sensor
  • Extended Starting Time. A malfunctioning IAT sensor may cause your vehicle to take longer to start on cold mornings.
  • Increase Fuel Consumption. The temperature of your vehicle's intake affects the amount of fuel needed to properly operate the car.
  • Check Engine Light.

What does a coolant temp sensor do?

A coolant temperature sensor is confined to the engine of a vehicle. This device measures the temperature of the vehicle's engine coolant. The sensor detects the temperature of this coolant and feeds this information back in the form of an electrical current to the engine control unit (ECU).
