Accurate intake air temperature measurement helps your engine run cleaner, smoother, and more efficiently. This Intake Air Temperature (IAT) Sensor monitors the temperature of incoming air and delivers a precise electrical signal to the engine control unit (ECU). The ECU uses that data to adjust fuel delivery, ignition timing, and emissions control — improving idle stability, cold starts, fuel economy, and overall drivability. Key benefits Restores correct airtemperature input to the ECU so fuel trims and timing stay accurate. Improves coldstart performance and reduces unwanted rich/lean conditions caused by a faulty sensor. Helps reduce emissions and prevents engine warning lights related to airtemperature faults. Simple replacement: OEstyle fit and performance for reliable, longterm operation. What it does and why you need it Measures the temperature of intake air and converts it to an electrical signal the ECU can read. A defective or outofspec IAT sensor can cause poor fuel economy, rough idle, stalling, or a check engine light. Replacing it restores correct sensor data and engine control logic. Ideal for both routine maintenance and troubleshooting drivability issues linked to airtemperature readings. Key attributes Functionality: Produces a temperaturedependent resistance/signal compatible with standard automotive ECUs; designed to match factory response characteristics. Construction: Durable, weatherresistant housing with a sealed sensor element; built to withstand enginebay heat, vibration, and exposure to contaminants. Connector and fit: OEstyle electrical connector and mounting interface for straightforward plugandplay replacement. Matches factory mechanical and electrical connection points when part numbers align. Performance: Fast response to temperature changes for timely ECU adjustments; stable output across normal operating conditions. Size and installation: Compact sensor body for installation in air intake ducts, intake manifold, or throttle body ports where OEM sensors are located. Installs using the vehicle's existing mounting point and harness. Compatibility and fitment Designed to be a direct replacement for vehicles that use this style of IAT sensor. Compatibility depends on matching the original equipment (OE) part number, connector type, and mounting style. Before , confirm fitment by comparing your vehicle's OEM part number, connector pin count, and physical mounting to this sensor. Use cases and applications Routine replacement: Swap a degraded or failed IAT sensor to clear fault codes, restore fuel trim accuracy, and eliminate drivability complaints. Diagnostics and : Use when diagnosing coldstart enrichment, rough idle, or checkengine codes related to intake air temperature or sensor circuit performance. Performance upgrades and intake changes: Install when adding or changing intake components that require an intact temperature feedback signal for the ECU to maintain air–fuel ratio and timing. Installation notes Installation is typically straightforward: disconnect the battery (recommended), unplug the electrical connector, remove the old sensor, install the replacement, and reconnect. Tighten to the vehicle manufacturer's torque specification. If a fault code persists after installation, verify connector continuity, wiring, and proper grounding, and clear stored codes with a diagnostic tool. Quality and reliability Built to meet automotive operating conditions with corrosionresistant materials and a sealed sensing element for consistent, longlasting performance. Matches factory electrical characteristics when used as a likeforlike replacement to ensure proper ECU calibration and behavior. Before you Verify compatibility by matching the part to your vehicle's year, make, model, engine, and OEM part number. This product is intended as a directreplacementstyle IAT sensor and must match the original sensor's connector and mounting to ensure correct fit and function.
