Sensors

Delphi's Air Temperature Sensors are continuous function devices that change resistance inversely to temperature. They measure engine intake air temperature in the manifold, intake air duct, and air cleaner. A signal is then sent to the powertrain control module. Two versions are available:

• Intake Air Temperature Sensor
• Manifold Air Temperature Sensor
  

Benefits

• High-temperature thermoplastic shell for durability
• Patented, lightweight, and cost-effective pre-mold subassembly
• Design flexibility to match calibration criteria, meet mounting and packaging requirements, and integrate with systems
• Customized packaging of mounting features, sealing options, connection system, and resistance output
• Crimpless conductive path to the negative temperature coefficient thermistor and calibration certification for enhanced reliability and accuracy; also eliminates an electrical interface
• 100 percent resistance calibration verification helps ensure quality and reliability
