• Specifications:
  • Dimensions: 6.29" × 3.93" × 0.39" 
    
• Functions:
  • Turbocharger control 
    
  • Measures air pressure
    
  • Air-fuel mixture adjustment
    
  • Data signal to engine control unit (ECU): The sensor converts the measured air pressure into an electrical signal. This signal is then transmitted to the Engine Control Unit (ECU), the vehicle's primary computer.
    
  • Higher altitude (lower air pressure): At higher altitudes, the air is thinner, resulting in less oxygen available. The ECU adjusts the air-fuel mixture to richen it (more fuel, less air) to ensure proper engine performance despite the reduced oxygen density.
    
  • Lower altitude (higher air pressure): At lower altitudes, there is denser air, meaning more oxygen molecules are available for combustion. The ECU adjusts the air-fuel mixture to compensate, allowing for a slightly leaner mixture (more air, less fuel) while maintaining engine performance.
