What would cause my 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. ... Disconnect the temperature sensor's wiring connector.

Is there a fuse for the temperature gauge?

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.

What does it mean when your temperature gauge stays on cold?

On most vehicles, the temperature gauge reads cold until the engine has run for a few minutes. If the temperature gauge still reads cold after the engine has warmed up, the gauge may simply be broken. ... With the thermostat stuck open, the engine can be overcooled, causing a low temperature reading.

How do I know if my temperature sensor is bad?

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

  1. Poor Fuel Economy. ...
  2. Irregular Temperature Readings. ...
  3. Black Smoke from Your Exhaust. ...

What causes a thermostat to fail?

Once the coolant engine reaches proper operating temperature, typically 180 to 200 degrees, the thermostat opens up and allows the coolant to flow through the engine. Sometimes the thermostat fails and must be replaced; there are four main reasons for failure: overheating, sludge, defect and age.

How much does it cost to fix a temperature gauge?

To have this sensor replaced, you will pay somewhere between $95 and $140, depending both on the car you have and the mechanic's fees. The labor should cost between $60 and $80, while parts can cost as little as $35 or as much as $65.

  6. Check the fuses inside the car.

How do you know if your thermostat is stuck open?

Symptoms of a bad thermostat

Thermostat stuck open: When the thermostat is stuck open, the engine temperature drops below normal when driving, especially on the highway in cold weather. A stuck-open thermostat can also cause lack of heat from the heating system. The Check Engine light may come on too.

Should my temperature gauge be in the middle?

The ideal engine temperature should be somewhere between 195 and 220 degrees. An engine is operating normally when the needle points at the center or near the center of the gauge. Don't worry if the needle does not exactly sit in the middle of the gauge.

Can you drive a car with a stuck thermostat?
