  Q: What does the Manifold Absolute Pressure (MAP) sensor or the Manifold Differential Pressure (MDP) sensor do?

  A: The Manifold Absolute Pressure (MAP) sensor or the Manifold Differential Pressure (MDP) sensor monitors changes in pressure inside the intake manifold and converts this information into a variable voltage output to the PCM. The PCM sends a 5-volt reference voltage to the sensor and uses the signal to monitor changes in intake manifold pressure.
