I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.the first two are mixture codes - usually an air leak, failed crankcase vent valve, failed airflow sensor, bad temp sensor or bad o2 sensors.
the third code is for a catalytic converter issue - possibly a bad cat, bad o2 sensors or exhaust leak near an o2 sensor
Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
