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 in a car?
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:
How much does it cost to fix a temperature gauge?
The average cost for an engine temperature sensor replacement is between $150 and $193. Labor costs are between $82 and $105 and parts are between $66 and $88. via
How do I know if my temperature sensor is working?
How much does it cost to replace a coolant temperature sensor?
The average price for an engine temperature sensor replacement is between $150 and $193. Labor costs are between $82 and $105 while parts are between $66 and $88. Taxes and fees aren't included in the estimate. via

Can you bypass a temperature sensor?
You can bypass it with a regular resistor, but you have to know the value associated with the thermister. To find the value: -Disconnect the thermister, and apply a meter to it and read initial resistance value. via
What happens if a temperature sensor goes bad?
If the coolant temperature sensor malfunctions, it can transmit a false signal to the computer. And the response of the computer may unbalance the timing and fuel calculations. It is also common for a coolant temperature sensor to fail without warning and send permanently cold signals to the computer. via
Can you drive with a faulty coolant temperature sensor?
Yes, you can drive with a bad coolant temperature sensor. When the coolant temperature sensor goes bad the ECU of the car defaults to a static reading. But it is not recommended to keep driving with a bad engine coolant temperature sensor since it performs critical cooling, heating, and fuel adjustment functions. via
Does the coolant temp sensor control the thermostat?
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. via
How do I check my temperature gauge? (video)
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 test a temperature sensor on a car? (video)
How do you calibrate a temperature sensor? (video)
How long does a coolant temperature sensor last?
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
How do you change a coolant temperature sensor?
How is P0128 diagnosed?
The most common cause for P0128 is the engine coolant thermostat is stuck open. A simple way to diagnose this is to feel the radiator hose and monitor how hot the temperature of the coolant is when it starts flowing through the radiator hose. via
How do I know if my coolant is circulating?
Start your car's engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open. via
What happens when the thermostat is stuck closed?
Your vehicle's thermostat opens to allow coolant to flow through the radiator and cool the engine down. However, if the thermostat gets stuck in the closed position, the coolant can't flow through the radiator and can make your engine overheat. via
How do I know if my water pump is circulating? (video)

How many temperature sensors does a car have?
There are 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. via
Where is the coolant temp sensor most commonly located?
The engine coolant temperature sensor is usually located on the engine block or cylinder head. It is often installed on a plastic hose on the coolant's inlet. Different brands and car manufacturers have different ways of placing the coolant temperature sensor depending on the car design. via
How do I disconnect my coolant sensor? (video)
Will a temp sensor keep car from starting?
The sensor will not cause a no start. It could cause a hard start and a rich or lean condition only. via
How do you fix a thermistor? (video)
What sensor controls the temperature gauge?
A coolant temperature sensor (CTS) (also known as an ECT sensor or ECTS (engine coolant temperature sensor) is used to measure the temperature of the coolant/antifreeze mix in the cooling system, giving an indication of how much heat the engine is giving off. via
Do you need to drain coolant to change coolant temperature sensor?
Do you need to drain coolant to change coolant temperature sensor? Open the radiator valve and drain about two to three quarts of coolant. You only need to remove enough to drop the level below the sensor. via
How long does it take to replace temperature sensor?
How long does it take to replace a coolant sensor? In most cases, it is 5 to 10 minutes, once you have the right wrench in your hand and the sensor in the other. via
