Manifold Absolute Pressure Sensor for Case Magnum Series Tractors SKU: QT400091

When this air sensor fails, your Case Magnum's engine management system loses the critical manifold pressure data it needs to optimize fuel delivery and timing. The result is reduced power, poor fuel economy, rough idle, or fault codes that can shut down operations during critical work periods. This replacement air sensor restores the precise pressure monitoring your turbocharged engine depends on.

Why Precise Sensing Matters

• Provides accurate intake manifold pressure data for optimal engine performance
• Essential for proper fuel injection timing and air-fuel ratio calculations
• Built to handle the heat and vibration of demanding agricultural applications
• Direct replacement ensures compatibility with Case Magnum electronic control systems

A faulty manifold pressure sensor affects more than just performance—it can trigger limp mode and leave you stranded in the field. This replacement sensor gets your Magnum running at full capacity again. Trust S&H Parts' 55+ years of experience to keep your operation moving forward.
