Where is the radiator temperature sensor located?
It is most often located close to the thermostat of the cooling system or inside of it. The cooling system is located beneath the air intake pipe and behind the right cylinder.
What sensor is next to the coolant temperature sensor?
It is called the "coolant temperature sensor." The one nearer the back with one wire drives the temperature gauge on the dash. It is the "coolant temperature sender." There is even another sensor, the "coolant temperature switch" which turns the radiator fan on when the engine is getting too hot.
What sensor controls the temperature gauge?
To troubleshoot your car's temperature gauge, you need to know how it works. The temperature gauge reading starts out as a reference voltage that is sent to the coolant temperature sensor. This sensor is nothing more than a thermistor -- a variable resistor that changes resistance with temperature changes.
What happens if you unplug the coolant temp sensor?
What Happens If You Unplug The Coolant Temp Sensor? Unplugging the engine coolant sensor while the car is running will likely cause the engine to stumble and run rough. The engine light may not come on imminently, but a DTC (Diagnostic Trouble Code) will be logged in the PCM.
How many coolant temperature sensors are in a car?
You have two separate temperature sensors for the fans, dashboard gauge, and engine management in most cars. However, if your car has a single sensor, a bad engine coolant temperature sensor may result in your fans won't start at all.
Does the coolant temp sensor control the fan?
On most modern cars, the cooling fan is controlled by the Engine Control Unit (ECU) which gets a signal from the coolant temperature sensor. If it's not working, the fan won't turn on when it needs to, which means the engine might overheat.
Can a coolant temp sensor keep a car from starting?
The sensor will not cause a no start. It could cause a hard start and a rich or lean condition only.
Why is my temperature gauge stuck on hot?
Common reasons for this to happen: Low Coolant: The first suspected cause of your temperature gauge maxing out is low coolant. ... The needle may be stuck in the hot range (this can happen after overheating the engine), or a stepper gear in the gauge may be damaged.
What would cause my temperature gauge to stop working?
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.
How do you test a temperature sensor?
Gently lower the end of the sensor into the water until the entire device is fully submerged. Wait a minute or so for the screen to give you a reading of the cold water. Once you have a reading, write down the measurement for reference. A common reading for a temperature sensor in cold water is around 5 volts.
How many wires should be in a coolant temp sensor?
The engine coolant temperature sensor is temperature-variable resistor, which usually has a negative temperature coefficient. It is a two-wire thermistor immersed in coolant and measures its temperature.
How does 2 wire coolant sensor work?
Two-wire temperature transmitters are widely used in modern industrial measurement and control systems. The transmitter can be combined with a thermal resistor and a thermocouple to linearly convert the temperature signal into a 4-20mA DC standard output current signal and modulate it on two power lines.
