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

A faulty ECT sensor can send a false signal to the onboard computer, resulting in an incorrect air-fuel mixture. For example, a faulty sensor can send a signal indicating the engine is cold when it is not, and more fuel will heat the engine quickly.

It is possible to drive a vehicle with a faulty coolant temperature sensor as the management system defaults to a static reading. A vehicles coolant sensor is a critical component used by the engine management system.

1. Poor Fuel Economy.
2. Irregular Temperature Readings.
3. Black Smoke from Your Exhaust.
4. Your Engine is Overheating.
5. Your Check Engine Light is On.

Most automobile mechanics will tell you it is not a good idea to drive your car without a thermostat installed. If your thermostat becomes stuck in the closed position, though, this will cause your engine to overheat and make driving your car impossible.

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

As such, you should never drive your vehicle if the cooling fan isn’t working even though you can. If the radiator does not have cool air blowing on it constantly, it will overheat eventually, so you’d need the perfect combination of weather and traffic to drive effectively without a radiator fan.

Six things may prevent an electric cooling fan from coming on: Defective temperature switch, coolant sensor or other sensor. Engine thermostat is stuck OPEN (engine never gets hot enough to turn on the fan) Faulty fan relay.

If the fan doesn’t come on, you need to look for a blown fuse or breaker. In older cars, you might have a fusible link – this is wire within an insulated block of rubber. Try to grab the end and stretch it. If the wire stretches, the wire link could be broken and you’ll need to replace it.

Floor Fan Stopped Working? Your Troubleshooting Guide

1. Check the Cord. It sounds simple, but your first step should be to make sure the cord is securely plugged in.
2. Check Your Circuit Breaker.
3. Check for Power to Your Outlet.
4. Check the Fan Fuse.
5. Replace the Cord.
6. Clean the Fan.
7. Grease the Motor.
8. Call Customer Support.

The fan may not be working because it has been overused and has overheated. Try unplugging the fan for at least 15 minutes, and then plug in the fan again. When you do this, make sure the fan is OFF while it is resting. Also, make sure you turn the fan to ON after plugging it back in.
