Walker Products 225-1074 Manifold Absolute Pressure Sensor

The Manifold Absolute Pressure Sensor (MAP) measures manifold pressure through changing voltage and sends the information to the vehicle’s onboard computer. The computer uses this and other inputs to calculate the correct amount of fuel delivered to the cylinders. The Barometric Pressure Sensor (BPS), also known as the Barometric Air Pressure Sensor (BAP), measures the atmospheric pressure of the environment and sends this information to the vehicle’s ECU. Vehicles driving in high altitudes where the air is thinner means less oxygen for the engine during the intake stroke. The BAP senses this and sends a message to adjust the amount of fuel accordingly. The BAP works closely with the MAP to determine the best timing and fuel conditions for optimum engine performance.
