Manifold Absolute Pressure (MAP/TMAP)

Manifold absolute pressure sensors (MAP) are used to measure the manifold pressure to determine the air density to calculate the engine’s air mass flow rate. The ECU is able to utilize this information to optimize combustion and ignition timing. MAP sensors often times are mounted in the exhaust gas flow and require immunity to harsh gases and chemicals. SMI has a variety of solutions to this challenging application to address varying levels of robustness.
