Understanding Your Car Sensors

Instructions From Driving Companies

Cars are complex works of engineering. They contain many parts that need to function perfectly so you can start up and drive your car. Sensors are present on the dashboard to inform you of the operational state of various key elements of the car.


These are the most important sensors you should pay attention to:


  1. Fuel Level Sensor

You should check this sensor before you start on any journey, as taught at instruction schools like MasterDrive in Fort Collins. If it indicates low fuel level, you should go to a gas station, first things first.


  1. O2 Sensor

This sensor indicates the level of oxygen in the exhaust system. Proper combustion inside the cylinder will leave very little oxygen in the exhaust gas. If the O2 sensor indicates a high level of oxygen, you are probably not using the right type of fuel or there is a problem in the combustion chamber.


  1. Mass Air Flow (MAF) Sensor

This sensor measures how much air enters the engine. This information is important for the drivetrain computer to determine the fuel metering and delivery into the combustion chamber. If you get a warning from the MAF sensor, it means that the engine is about to stall.


  1. Fuel Temperature Sensor

The warmer fuel is in the tank, the easier it will ignite. This is why your car takes so much time to start up during cold winter days. If the fuel is too cold for other reasons, you will get a “check engine” warning on the dashboard. Also, you will get lower mileage until the problem is fixed.
