比亚迪/吉利/华普/长城水温传感器 371QA-3611100 电喷系统专用温度信号采集

Temperature sensor dedicated to fuel-injected systems for BYD, Geely, Haval, Great Wall and other models (OEM 371QA-3611100) captures engine coolant temperature and converts it to an electrical signal for ECU to adjust fuel injection and ignition timing. Direct replacement of OEM part; universal compatibility across many models. After installation, it resolves cold-start difficulties, rough idle, or higher fuel consumption due to aging sensor misreporting temperature. If the temperature gauge fluctuates wildly, engine stalls easily, or a fault light stays on, this part likely needs replacement.
