What Do the Sensors in Your Vehicle Do?

The newer the car, the more advanced in technology its operating systems will be. Did you know that your vehicle has numerous sensors throughout its systems? They are connected to your car's internal computer, and they're there to serve one goal: communicate if there are any existing and potential problems with its associated vehicle components. 


Unfortunately, just like any other car part, sensors can fail and produce false alerts. In most cases, they'll do what they are supposed to do in order in your best interest. Some cars have more sensors than others, and certain manufacturers will tweak their sensor tech over the years. However, here are some of the most popular automotive sensors that you should be aware of:


Oxygen Sensor: The O2 sensor can be found in the exhaust system and monitors the corresponding levels of oxygen to the exhaust gasses being discharged from the engine. It assists the vehicle's computer system in regulating emission controls and detecting an imbalance in emissions.

Engine Speed Sensor: This detector measures the engine's RPMs and plays an integral role in ensuring engine efficiency. If the RPMs are too low or high then it could signify engine problems.

Manifold Absolute Pressure (MAP) Sensor: The MAP sensor tests for fluctuations in air pressure entering your engine to deliver the precise combination of fuel and spark.

Mass Air Flow (MAF) Sensor: The MAF detector measures the air volume and density entering your engine. It works in unison with the oxygen sensor to regulate the engine's proper flow of air and gas.

Fuel Temperature Sensor: Your vehicle will have a harder time burning cold fuel than warm fuel. This sensor observes the fuel temperature so that it can ensure a seamless combustion process.

Anti-Lock Brake Systems (ABS) Sensor: This sensor matches relative wheel rotation speed and prevents your brakes from locking up.

Tire Pressure Sensor: This modern tool helps to monitor the air pressure in all your tires and will notify you if any tires are low on air.


These are just a few of the many sensors you'll find in today's vehicles. You may need to have your sensors reset or replaced to ensure peak performance from time to time.
