The MAP sensor is located on the firewall. You can find it by looking at the intake manifold and following the vacuum lines that come out of it to a black cigarette-box or smaller sized sensor. The Manifold Absolute Pressure sensor measures the air pressure inside the intake manifold vs. the atmospheric air pressure to maintain an optimum fuel-air mixture.
