Hi all,

Recently got the "increased emissions" error popup on my car with the check engine light.

Ran the codes and it gave me the following:

2B59 - Coolant thermostat monitoring

2771 - Oxygen sensor dynamic diagnosis bank 1

2772 - Oxygen sensor before cat bank 2.

Anyone could help me with what the issue is thats causing this? The check engine light + increased emissions error went off after ~2-3 days and then came back on and went off again.

Thanks in advance!
