Air Intake Temperature Sensor | HITTMS0003

The Hitachi TMS0003 Air Intake Temperature Sensor is a precision automotive sensor that measures the temperature of air entering the engine’s intake system. By providing accurate air temperature data to the engine control module (ECM), this sensor helps optimize fuel delivery, ignition timing, and overall engine efficiency. Designed and manufactured to meet original equipment specifications, the TMS0003 delivers reliable performance, improved drivability, and consistent engine response across varying environmental conditions. It is a direct‑fit replacement for factory intake air temperature sensors on compatible vehicles.

• Precise Intake Air Temperature Monitoring – Measures the temperature of incoming air for accurate engine management and optimal combustion.
• Improves Engine Efficiency – Helps the ECM make correct fuel and ignition adjustments for better fuel economy and smoother performance.
• Supports Emissions Control – Accurate temperature data plays a role in maintaining proper air‑fuel mixture and reducing emissions.
• OE‑Style Fit & Function – Designed to meet or exceed original equipment specifications for direct, bolt‑in installation.
• Durable Construction – Built with high‑quality materials and a thermistor sensor element to withstand engine bay heat and vibration.
• Reliable Signal Output – Negative temperature coefficient (NTC) thermistor design delivers consistent, accurate readings.
• Easy Replacement – Direct‑fit design with OE‑style connector means quick installation with no modifications.
• Resolves Performance Issues – Helps correct rough idle, poor fuel economy, and check engine codes related to air temperature readings.
