Sensor - Intake Air Temp

The Sensor - Intake Air Temp is a precision electric temperature sending unit engineered for GM engine management systems requiring real-time intake air temperature monitoring. Purpose-built for both field maintenance and OEM replacement applications, this digital sensor delivers critical thermal data to engine control modules, enabling adaptive fuel mapping and ignition timing adjustments. Law enforcement, military motor pool operations, and civilian fleet managers depend on accurate air intake diagnostics to maintain engine reliability, fuel economy, and emission compliance across demanding duty cycles.

This temperature sending unit features a 3/8 inch NPT brass connection, designed to thread directly into OEM intake manifold or air intake passages on compatible GM platforms. The electric digital interface allows seamless integration with factory engine control computers, providing instantaneous thermal feedback without mechanical gauge lag. Brass construction resists corrosion in high-heat engine bay environments, while the compact 3.75 x 1.1 x 4.65 inch profile ensures installation clearance in tight underhood spaces. The sensor's lightweight design at 0.07 lbs minimizes vibration-induced signal noise, critical for maintaining signal integrity during high-RPM or transient operating conditions.

Technicians, fleet maintenance personnel, and powertrain specialists will find this unit essential for diagnosing cold-start enrichment issues, turbocharger heat soak, and fuel trim anomalies tied to inaccurate air temperature readings. Installation requires only a standard wrench and basic electrical connector attachment; no programming or calibration needed on most GM applications. Verify OEM part compatibility and intake port thread specifications before ordering to ensure proper fit and sealing. This replacement sensor is ideal for vehicles experiencing check-engine codes related to intake air temperature circuit faults or those undergoing engine bay restoration work.
