MAP Sensors

The Manifold Absolute Pressure (MAP) Sensor can come in many shapes and sizes, and are usually mounted to your intake manifold or throttle body. The role of this sensor is to read the amount of vacuum or pressure in the intake tract. This amount is then converted into voltage that your engine's electronic control unit (ECU) can use to orchestrate the fuel delivery of your car or truck.

CAN'T FIND YOUR MAP SENSOR BELOW? TRY SEARCHING FOR YOUR YEAR, MAKE OR MODEL. GOOD EXAMPLES ARE "2000 Acura Integra MAP Sensor" or, "2012 Cadillac ATS MAP Sensor" AS SEARCH TERMS.

While this sounds simple, the process of collecting the data and calculating air density and pressure to maintain optimum performance is in fact very complex. If you are interested in learning about your MAP sensor and how it controls the closed loop operation of your vehicle, head over to My Pro Street for more information.
