Hello my name is Philip I own a 2004 X5 check engine light is on. Problem with oxygen sensor I changed both but the light still on. Please help

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your vehicle. Even after replacing the oxygen sensors in your X5, the check engine light coming back could mean the issue lies elsewhere in the system. Check for exhaust leaks near the sensors, which can throw off the readings. Also, the catalytic converter might be underperforming, or there could be a wiring or connection issue with the sensors. A faulty mass airflow sensor or intake air leak can also cause incorrect oxygen sensor readings. Running another scan for updated codes will help pinpoint the next step. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
