The Simard Automotive Guide to Vehicle Sensors

Your vehicle is equipped with numerous sensors to help notify you when there is a potential problem. The more advanced and modern your car is, the more sensors it will likely have. They are connected directly to the computer system. They are there to help make sure the vehicle performs its best while also to warn if something is wrong.

Sensors can sometimes produce faulty warnings if not calibrated correctly. Or, the sensors can fail altogether and will need to be replaced. They are just like any automotive component that can wear out with time. Every vehicle manufacturer will have different systems and sensors they might use, and almost every car will be a little different, as well. However, Simard Automotive has put together this list of the most common sensors that you will find in many of today’s cars, trucks and SUVs.

Oxygen Sensor – This is part of the exhaust system. It monitors the relative amount of exhaust gasses to oxygen. The car’s computer system will balance the fuel efficiency and emissions based on the info provided by the oxygen sensor(s).

Manifold Absolute Pressure (MAP) Sensor – In order for the engine to provide the right combination of fuel and spark, the MAP sensor will check for air pressure variations as air enters the engine.

Fuel Temperature Sensor – Fuel needs to flow into the engine at proper temperatures. Colder fuel doesn’t burn as well while hotter fuel may burn too quickly. This sensor helps regulate the fuel temperature.

Engine Speed Sensor – This sensor monitors the RPMs of the engine. It helps make sure the engine is running as efficiently as possible.

Mass Air Flow (MAF) Sensor – It works in conjunction with the oxygen sensor to monitor the volume and density of air as it enters and exits the engine.

Tire Pressure Sensor – Most vehicles have tire pressure sensors that will notify you if the air pressure in any (or all) of the tires is too low.

Anti-Lock Brake Systems (ABS) Sensor – This keeps the brakes from locking up when you come to a stop by comparing relative wheel rotation speed.

Intake Air Temperature (IAT) Sensor – The computer can regulate exhaust gas recirculation and improved emissions thanks to the IAT sensor.

This list represents just some of the most common automotive sensors found in today’s vehicles. They all perform specific functions to help keep your car running its best. If your check engine light or any other warning light is tripped, it’s usually because one of these sensors has detected a problem or is malfunctioning. Bring your vehicle into Simard Automotive for thorough diagnostic testing, inspection and automotive repairs.
