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
