What is your question?
Check engine light came on then went off the next day. It keeps doing this. What's the problem?

*Hands-on* / visual inspection of wiring harness and connector to downstream HEATED OXYGEN SENSOR (sensor 2) .. Professional quality scan tool for monitoring 02 sensor readings is a must. You’ll likely need hands- on assistance from qualified personnel for the required testing. Good luck!
Posted symptoms are indicative of intermittent wiring circuit failure to 02 sensor. That only a guess without testing confirmation.
