Dorman 904-7250 Ambient Air Pressure Sensor

Ambient Air Pressure Sensor

The barometric pressure sensor is an essential component of the vehicle's engine management system. The primary function of the BAP sensor is to measure the atmospheric pressure and temperature of the environment the car is driving in, making necessary adjustments to the fuel trim and engine timing. Monitoring the air pressure and temperature outside of the engine is critical for better overall vehicle performance, helping to prevent acceleration issues, stalling, and costly engine damage.
