What would cause your temperature gauge not to work?

The most common cause of faulty temperature readings is a broken coolant temperature sensor (CTS). The part, which is normally located near a vehicle's thermostat near the base of the radiator (consult your owner's manual or repair guide) can get gunked up and fail. via

What does it mean when the temperature gauge doesn't move?

The most common reason your temperature gauge staying on cold is a faulty coolant temperature sensor. It can also be caused by bad wirings between the cluster or the sensor. In some cases, it can also be a stuck thermostat causing the engine not to heat up properly. via

Is there a fuse for the temperature gauge?

There isn't one per se. There will be a fused wire with voltage to the instrument cluster (your owners manual should indicate which fuse), but the temperature sensor is providing a variable "resistance to ground," which the temperature gauge in the dash is reflecting. via

What are the signs of a failing temperature sensor?

Following are the significant symptoms of a bad coolant temp sensor:

  • Check Engine Light.
  • Engine Overheating.
  • Poor Fuel Economy.
  • Poor Engine Performance.
  • Broken Water Pump.
  • Control of Cooling Fan.
  • Black Smoke From Exhaust Pipe.

    Is there a fuse for the coolant temp sensor?

    In general, there are not many. Depending on the vehicle's model year, there will either be a wire fused with voltage to the instrument cluster or a sensor that detects resistance to ground with the temperature sensor recording its position at the touch of a button on the dashboard. via

    When should I worry about my temperature gauge?

    If the temperature gauge consistently shows the engine is warmer than normal, have your cooling system checked ASAP. There are many possible reasons that your engine is running hot, including low coolant levels, a clogged or closed thermostat, a failed head gasket or a water pump malfunction. via

    How do you check engine temperature?

    Start your car's engine and allow it to idle. Use a cooking thermometer or a hydrometer to obtain a temperature reading from the engine block (also known as the cylinder block) and the upper radiator hose. The end of this hose will be attached to the thermostat housing. via

    When should I replace my coolant temperature sensor?

    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. via

    Can a bad coolant temperature sensor cause overheating?

    If the coolant temperature sensor malfunctions, it could cause your car engine to get overheated. While sometimes a faulty sensor sends a permanent cold signal to the engine, it can also send a permanent hot signal. via

    How many temperature sensors does a car have?

    All it takes is ONE hit. There may be 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. However, some vehicles dispense with the need for two temperature sensors by using just one sensor to do both tasks. via

    How do you check a coolant temperature switch? (video)

    Why is my car reading the wrong outside temperature?

    The sensor that measures outside temperature is typically up behind the bumper, which is near the hot asphalt and the engine. That's why it reads a little higher that what the temperature actually is outside. via

    What causes low engine temperature?

    The most common reasons for the temperature to remain low include: A thermostat stuck open. A bad engine coolant temperature sensor. A locked fan clutch. via

    What does it mean when your temperature gauge is low?

    On most vehicles, the temperature gauge reads cold until the engine has been running for a few minutes. If after the vehicle is warmed up, and the temperature is still reading cold, the temperature gauge may be broken. Another reason the temperature gauge is reading low is if the thermostat in the vehicle stays open. via

    How do you know if your car is overheating?

  • Hot Hood. When the engine is running, you can expect the hood to emit heat and feel warm to the touch.
  • Temperature Gauge or Light.
  • Ticking Noise.
  • Coolant Leaking on the Ground.
  • Smells “Hot”
  • Steam Coming from the Hood.
  • Thumping Noises.
  • Reduced Engine Power.
