The temperature sensor on a Ford Fiesta is the coolant temperature sensor. It is located in the coolant pipe, below the air intake and behind the right cylinder head . The coolant temperature sensor plays a vital role in regulating the temperature of the vehicle and contributes to the overall strength and longevity of the car. It monitors the temperature of the coolant circulating in the engine and sends this data to the car’s main computer. Based on this information, the computer determines how much fuel and air should be injected into the engine and whether to turn on the cooling fans.

What happens if temp sensor goes bad?
The coolant temperature sensor can fail and transmit cold signals to the computer. This action confuses the computer and stimulates it to enrich the fuel mixture unnecessarily. This can cause the fuel mixture to be vibrant such that during combustion, the fuel can’t be adequately consumed within the chamber.
Is coolant temperature sensor easy to replace?
Yes, it’s extremely easy but also very dangerous. It is shaped like a big bolt and simply unscrews from the socket. But if this is done when the vehicle is hot it will spray out boiling coolant. So the vehicle must be allowed to sit and cool down with the radiator cap off before changing the sensor.
Does the coolant temperature sensor control the fan?
Yes, the coolant temperature sensor is an important component in controlling the radiator fan in many modern vehicles. The coolant temperature sensor monitors the temperature of the engine coolant and sends this information to the engine control module (ECM), which uses it to determine when to turn on the radiator fan.
How do I know if my car temperature sensor is bad?
If the computer detects that the engine is heating up too much, the performance settings will be adjusted to prevent overheating.
- Faulty Coolant Temperature Sensor – 4 Common Symptoms.
- Fuel Consumption Increases.
- Check Engine Light Flashes.
- Engine Overheating.
- Black Smoke from the Exhaust.
- Don’t Ignore the Warning Signs.
What happens if you unplug the coolant temp sensor?
If you are unplugging your vehicle’s coolant temperature sensor, you will definitely run into some problems. you will set a trouble code, check engine light on, radiator cooling fan should come on. Don’t drive car with the sensor disconnected.
Will a temp sensor throw a code?
Possible bad Coolant temp sensor. Since the temp gauge doesn’t go to the normal range the car is most likely getting out of range readings from this sensor(such has -40°C) and it will then throw a code like P0115 which means Engine Coolant Temperature Sensor Malfunction.
What is the temperature warning light on a Ford Fiesta?
Ford engine coolant temperature warning light
This light will come on when the engine is overheating. This could mean that coolant levels are running low, perhaps due to a leak in the system, or it could be a sign of a larger problem, like a head gasket failure.
Where is the temp control sensor located?
The ECT sensor is often located on the engine block, usually near the thermostat housing. On some engines, it may be located on the intake manifold. The sensor measures the temperature of the coolant and sends a signal to the computer. The computer uses this information to adjust the ignition timing and fuel mixture.
Can I drive with temperature warning light?
You should never ignore the engine temperature warning light. If the light illuminates on your dashboard, you’ll want to pull over and shut off the engine immediately. If the engine temperature warning light illuminates on your dashboard, it means your car’s engine is overheating.
Can I drive with a bad coolant temp sensor?
Driving with a bad coolant temperature sensor is not recommended, as it can lead to various problems and potential engine damage. The coolant temperature sensor plays a crucial role in monitoring the temperature of your engine’s coolant and providing this information to the engine control unit (ECU).
