Your Truck's emission parts fail due to wear and engine heat. A manifold absolute pressure sensor is a type of sensor that measures the changes taking place in engine manifold pressures. Although it is used to determine the amount of pressure and density of air in the engine, it should not be confused with other sensors such as a barometric sensor and a mass airflow (MAF) sensor, which are used respectively in gauging high altitudes and the air flow and density required to come up with fuel adjustments.
