Guys,
Just wanted to confirm with everyone if this is indeed my issue or not:
I did my brake flush and that lead to a small leak around the reservoir cap.
After 10 days got reduced engine power with increased emissions.
Adding codes below - based on my research it seems quite clear that it is the brake booster sensor. Just need to understand why I am getting the Increased Emission? How can that be related to Brake Booster Sensor?
