What Does A Map Sensor Do. Simply put, a sensor is a device programmed to receive (or identify) a certain type of input by analyzing the surrounding environment. The manifold absolute pressure sensor ( MAP sensor) is one of the sensors used in an internal combustion engine 's electronic control system. The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine's electronic control unit (ECU). With the car off and the key on, the MAP sensor will read "zero" at sea level. The MAP sensor helps the computer understand the air density and therefore the engine's mass air flow. 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. Alternately mass air flow fuel injection systems use a dedicated mass air flow meter to accurately measure engine air flow. MAP sensors are set to "zero" from the factory.
What Does A Map Sensor Do. The MAP sensor test procedure is as follows: Check for MAP sensor trouble codes with a code reader or scan tool. Turn the engine off but keep the ignition on. VO: A MAP Sensor is a Manifold Absolute Pressure Sensor. The MAP sensor is usually found in the engine compartment mounted to the intake manifold or firewall. This video explains how a MAP sensors detect manifold pressure and use this informat. What Does A Map Sensor Do.
It is going to measure the amount of absolute pressure inside the intake manifold or the amount of vacuum.
The manifold pressure sensor transmits real-time manifold pressure data to the engine's electronic control unit (ECU).

What Does A Map Sensor Do. In some vehicles, a mass air flow (MAF) sensor is used. Alternately mass air flow fuel injection systems use a dedicated mass air flow meter to accurately measure engine air flow. The manifold absolute pressure sensor (MAP sensor) is one of the sensors used in the electronic control system of an internal combustion engine. MAP sensors measure the air pressure in your intake manifold, which helps the engine's computer determine air / fuel ratios. The MAP sensor test procedure is as follows: Check for MAP sensor trouble codes with a code reader or scan tool.
