3. Working Principle
Core Component: NTC negative temperature coefficient thermistor
Principle: Resistance decreases as temperature rises; resistance increases as temperature drops
Power Supply: 5V reference voltage supplied by ECU
Signal Output: Resistance change is converted into voltage signal for ECU to calculate intake air temperature
Temperature-Resistance Characteristics:
20℃ ≈ 2.5 kΩ
80℃ ≈ 0.5 kΩ
4. Technical Specifications
Measuring Range: -40℃ ~ +125℃
Accuracy: ±2℃ ~ ±5℃
Response Time: ≤ 150 ms (Quick response)
Connector Type: 2-pin waterproof connector (Oil-proof and well-sealed)
Installation Position: Intake manifold or pipeline after intercooler
Ingress Protection: IP67 (Dustproof and splash-proof)
5. Main Functions
Intake Air Temperature Monitoring: Real-time detection of air temperature entering the engine.
Fuel Injection Correction:
- Low temperature (high air density): Increase fuel injection volume for better cold start performance.
- High temperature (low air density): Reduce fuel injection volume to cut fuel consumption and optimize exhaust emission.
Ignition / Injection Timing Adjustment: Fine-tune timing according to temperature to prevent engine knocking and improve working efficiency.
Turbocharger Protection: Avoid turbo damage caused by overheated intake air.
6. Fault Consequences
Malfunction Symptoms: Difficult cold start, unstable idling, insufficient power, high fuel consumption and excessive exhaust emission.
ECU Trouble Codes: Fault codes such as P0110, P0111 will be recorded.
Long-term Impact: Accelerated engine wear and shortened service life of turbocharger.
