GM Sensors

Newer model General Motors cars, trucks, SUVs and crossovers all use computer systems and components in order to provide for optimal operating conditions and achieving the best performance. The computer systems function in a manner where data is fed into the computer and the computer processes this data to make adjustments to the operating conditions of the engine as well as other systems on the vehicle. One part which aids in taking data readings is a GM sensor and information collected is fed back into the computer.

A GM sensor can be found in several different areas on the vehicle and could include oxygen sensors, air pressure sensors and temperature sensors. Oxygen sensors are used to adjust the air and fuel mixture in order to obtain the best gas mileage possible. When the oxygen sensor malfunctions, inaccurate data is fed to the computer which could result in an increase in fuel consumption and decreased gas mileage. Air pressure sensors feed data about the different air pressures in the tires and ensures that correct air pressure levels are maintained.

Maintaining proper air pressure in the tires is important to extend the life of the tear, ensure for uniform tread wear and maintain higher levels of gas mileage. When one tire loses air pressure, A GM sensor reading will feed this data to the computer, which will then display a check tires message on the dash display in the vehicle. It is a good idea to stop driving and check the tire pressure on all the tires at that point, because a tire which is losing air could have a nail or other object in it and could result in a blow out if it is left unchecked.

A GM sensor is also used in General Motors vehicles to measure temperature readings for different features and systems on the vehicle. General Motors vehicles which display inside and outside temperatures use a temperature sensor to take the air temperature and feed the data to the computer which then converts this information and displays the results on the display on the dash in either Fahrenheit or Celsius.

A GM sensor used under the hood of the vehicle to measure air intake temperatures is another type of temperature sensor. As the engine heats up this sensor monitors both the engine temperature as well as the temperature of the air coming in through the air intake. Cooler air intakes temperatures help keep the engine cool and from overheating. When the outside air temperature is hot, then the cooling system on the vehicle must work harder in order to keep the engine operating and prevent it from overheating. In the event the engine becomes too hot, another temperature sensor sends this data to the computer, which then displays the results on the engine temperature gauge on the dash.

Over time sensors wear out and need replaced and can be obtain from Auto Parts Tomorrow, www.autopartstomorrow.com.
