The fuel temperature sensor is the sensor that senses when your engine and fuel are overheating. You don't want your car to overheat. It could result in it halting in the middle of nowhere or, worse, in the middle of the highway.
The sensor monitors temperature changes to ensure that your fuel consumption is at peak efficiency. The colder the fuel the denser and slower it burns. The hotter the fuel the thinner and faster it burns.
When it's too hot and your car runs out of fuel too quickly, many car and engine parts might get damaged. Not to mention that overheating is one of the worst things that can happen to your engine, so this sensor is a lifesaver in terms of fuel and engine safety.
The Remaining Sensor Roundup
- Voltage Sensor: The voltage sensor is a small but powerful sensor that's an important part of many a car sensors list. This is the sensor responsible for idling speed management. It also ensures that the speed is decreased or increased as needed.
- MAF Sensor: The Mass Air Flow sensor calculates the volume and density of the air taken in by the engine, otherwise known as the mass flow rate of air that enters a fuel-injected type of internal combustion engine. The engine control unit or ECU needs this sensor to deliver and balance the right fuel mass to the engine.
- Oxygen Sensor: This particular sensor measures the amount of unburdened oxygen found in the exhaust pipe for the sake of ensuring that the fuel combustion ratio of air and fuel isn't too rich or too lean. This sensor allows your car to dynamically adjust the air-fuel ratio for the sake of the optimal operation of the catalytic converters.
- Spark Knock Sensor: This sensor senses whenever the fuel is burned correctly or not by the quality of the spark produced. If there's a spark knock or detonation that's an erratic form of combustion, fuel efficiency ends up going down. The sensor essentially decreases the chances for detonation that can waste fuel and ruin the car.
- MAP Sensor: The Manifold Absolute Pressure or MAP Sensor is the sensor that measures the manifold pressure from the inside and outside of the car. From there, adjustments can be made of the MAP pressure becomes too low or too high. Once this malfunctions, you'll end up consuming excessive fuel and still have lack of power.
- Engine Speed Sensor: The speed of the engine is measured so that you can avoid making the spinning speed of your engine crankshaft spin too much that it will wear itself out or alert you if the crankshaft is spinning too little for whatever reason. Without it, the car can end up with strange symptoms like the transmission revving up before switching gears or harder-to-engage brakes even when coasting.
