菲亚特派力奥水温传感器46554621/L1014D，冷却温度精准监控

When your Fiat Pialo (Pialio) experiences cold-start difficulties, idle instability, abnormal fuel consumption, or dashboard water temperature gauge fluctuates, and check engine light on, the original water temperature sensor is aging. This sensor monitors coolant temperature in real time and feeds data to the ECU to precisely control injection, ignition timing, and cooling fan operation, ensuring engine stays at optimal temperature. OEM number 46554621; fits Fiat Pialo (including 1.3L, 1.5L). Installation: work with a cold engine, partially drain cooling liquid, remove old sensor, clean mounting hole, replace gasket, and tighten with appropriate torque to avoid thread damage.
