2013 Silverado codes

[Fitz1974]

Hi I’m new to the forum. I recently purchased a 2013 Silverado it has the 5.3 and around 120k on it. It runs great but I had a check engine light come on.  when I scanned it I came up with 2 codes 1 was P219A and the other was P015A anyone ever had this or could you give me a place to start diagnosing this.

thanks

Possible that your bank 2 upstream o2 sensors is becoming faulty and then it's tripping the air fuel ratio imbalance code for the other side.

You can run those code on the Internet, just type the code in and hit enter.... I'm in agreement with CamGTP, I think it's your O2 sensor but a Internet search will nail it a bit closer.
