Ford Edge Front Oxygen Sensor FR3A-9Y460-DA 0258017487

Ford Edge front oxygen sensor FR3A-9Y460-DA (compatible with 0258017487) installed between the exhaust manifold and catalytic converter, detects oxygen concentration in exhaust and sends signals to the ECU to achieve closed-loop control of the air-fuel ratio. Fits Ford Edge and several other models; replacing with the OEM part restores engine combustion efficiency. Use a dedicated socket during installation; torque about 45 N·m to avoid thread damage. Symptoms such as rough idle, delayed acceleration, or warning light illuminate usually indicate slow sensor response or heater failure.
