Product Details

The 225-1299 barometric pressure sensor is used in vehicle systems that monitor atmospheric pressure for accurate engine control.

What It Helps Address

  • Fault codes related to barometric pressure or manifold vacuum sensing
  • Rough idle caused by incorrect pressure input to the engine control system
  • Driveability concerns tied to inaccurate air-density readings
  • Hard starting or hesitation linked to sensor signal issues
  • Emission control faults triggered by a failing pressure sensor

Installation Notes

Verify the vehicle year, make, model, and sensor application before ordering. Use the existing connector and mounting location as the primary match points, and compare the original sensor shape and part number 225-1299 against the removed unit. For Mazda 3, Mazda CX-30, and Mazda MX-5 Miata applications, confirm the notes shown in the fitment data, including sensor-only listings where applicable.
