Automotive Map Sensor

Automotive Map Sensor. How Map Sensor Works Topographic Map of Usa with States In some cars, the MAF (Mass Air Flow) sensor is used to measure the flow of air entering the engine In fuel-injected automotive engines, a manifold absolute pressure (MAP) sensor is used to continuously monitor the amount of air flowing into the engine, so the computer can calculate air density, adjust the amount of fuel to spray into the combustion chamber and adjust the ignition timing

So, a map sensor measures the intake manifold pressure according to the vacuum present inside of the map sensor, that's why it is called manifold absolute pressure The manifold absolute pressure sensor (MAP sensor) is one of the sensors used in an internal combustion engine's electronic control system.

Technical info MAPSensors

It is going to measure the amount of absolute pressure inside the intake manifold or the amount of vacuum This is one way that modern vehicles ensure the best air fuel ratio for the internal combustion engine's performance. Now, I know most engines will have between 18 and 23 inches of vacuum.

What You Need to Know About a MAP Sensor Technician.Academy. The MAP sensor's function is to measure manifold pressure and send that data to the engine computer, which calculates air density and air mass flow rate to adjust fuel metering and ignition timing The more you hit the throttle, the closer to 0 psi the MAP sensor will read, because there is less vacuum in the intake manifold
