Toyota Previa Oxygen Sensor 89465-28280 Compatible with 28290/68070

Mate this: This water-temperature sensor directly replaces OEM SMW250119, also compatible with L1017-2 and HZ-SW-015; widely compatible with Buick Excelle, Chevrolet Lacetti, and Chevrolet Sail. Core function is real-time coolant temperature monitoring, sending signal to ECU to adjust fuel injection and fan on/off, ensuring engine runs within optimal temperature. After installation, it resolves inaccurate coolant gauge, cold-start difficulties, or rough idle, and reduces fuel consumption. If engine temperature fluctuates or fans run irregularly, sensor aging is the likely cause; replace to prevent major issues.
