Overview Haltech's M14x1.5 air temperature sensor delivers precise intake air density readings for optimal fuel and ignition mapping across all load conditions. This compact sensor threads directly into manifolds, intercooler pipework, or custom intake setups, providing the critical temperature data your Haltech ECU needs for accurate volumetric efficiency calculations and power delivery. Technical Specifications Part Number: HT-010200 Thread Size: M14 x 1.5mm Connector: Delphi plug with pre-crimped pins included Response Time: Fast-response thermistor element Temperature Range: -40°C to +150°C operating range Why You Need This Air temperature directly affects air density — and density changes mean your engine needs different fuel quantities to maintain target air-fuel ratios. Without accurate intake air temperature readings, your Haltech ECU is essentially guessing, leading to rich running in cold conditions and lean spikes when heat-soaked. This becomes critical on turbo builds where intercooler efficiency varies dramatically, or naturally aspirated setups where intake manifold heat affects power delivery. The M14x1.5 thread size makes this sensor perfect for Honda K-series manifolds, many aftermarket intake manifolds, and custom fabricated setups where space is at a premium. We see this constantly on SR20DET builds where the small sensor body clears brake master cylinders, and on LS swap projects where manifold real estate is limited. The included Delphi connector ensures reliable connections in engine bay environments — no cheap spade terminals that corrode or vibrate loose during hard driving. ECU & System Compatibility Compatible with the full Haltech Elite and Nexus range including Elite 550, 750, 1000, 1500, 2000, and 2500 ECUs, plus Nexus R3 and R5 systems. All Haltech ECUs feature dedicated air temperature sensor inputs with built-in pull-up resistors and calibration tables for this sensor. What's in the Box Haltech Air Temperature Sensor with M14x1.5 thread Delphi weatherpack connector Pre-crimped connector pins Complete Your Build Most customers fitting this air temp sensor also add our HT-010300 coolant temperature sensor for complete engine monitoring, and the HT-010100 GM 1 Bar MAP sensor for naturally aspirated or low-boost applications. If you're fabricating a custom intake setup, consider the HT-010230 weld fitting which provides a perfect threaded boss for this sensor.
