Looking for OEM 3M519F472AC 0258006573 upstream oxygen sensor for Ford Focus MK2, Mondeo, Volvo C30 S40 V50 Our heated 4-wire O2 lambda sensor offers plug-and-play installation, fixes check engine light, high fuel consumption and exhaust emission failure, factory OEM standard quality.

1. Introduction

The OEM 3M519F472AC 0258006573 oxygen sensor (also named lambda sensor) is a front upstream exhaust oxygen sensor manufactured to match original factory specifications for Ford and Volvo shared platform gasoline vehicles. Equipped with a built-in heating element, this 4-wire oxygen sensor rapidly reaches operating temperature after cold startup to monitor exhaust oxygen concentration in real time.

The ECU adjusts fuel injection volume and air-fuel ratio based on sensor feedback signal, which directly affects engine fuel economy, power output, three-way catalytic converter service life and vehicle exhaust inspection pass rate. When the original oxygen sensor ages or fails, replacing it with a high-quality 3M519F472AC 0258006573 O2 sensor is the most cost-effective repair solution.

4. Common Fault Symptoms Caused by Failed 3M519F472AC 0258006573 O2 Sensor

If your vehicle has the following problems, the front oxygen sensor is highly likely damaged:

1. Check Engine Light On: Diagnostic trouble codes P0131, P0132, P0133 (abnormal voltage, slow response of upstream oxygen sensor)
2. Significantly increased fuel consumption (15% – 30% higher than normal)
3. Rough idling, difficult cold start, weak acceleration
4. Obvious pungent odor from exhaust, excessive exhaust emissions leading to MOT test failure
5. Automatic transmission shift jerking

Timely replacement of the oxygen sensor can avoid secondary damage to the expensive three-way catalytic converter caused by abnormal air-fuel ratio.

5. Installation Guide & Tips

1. Cold Car Disassembly: Do not remove the oxygen sensor when the exhaust pipe is hot to prevent burns and thread seizure.
2. Anti-Seize Lubrication: Apply high-temperature anti-seize compound on the sensor thread to avoid rust locking for future disassembly.
3. Distinguish Front/Rear O2 Sensor: This 3M519F472AC 0258006573 is the pre-cat upstream sensor, cannot be interchanged with the rear downstream oxygen sensor.
4. Post-Replacement Operation: Clear fault codes via OBD diagnostic instrument after installation, let the engine idle for 5–10 minutes to complete ECU adaptive learning for stable signal output.
