I was helping out RB the other day and unplugged my upper right bank O2 sensor to make sure it would throw a code. It threw the standard P12xx code for the O2 but I got another code with it that I didn't pay much attention to at the time and I believe it was code P1015. I assumed it was related to the O2 and half ignored it. After I cleared the codes I went ahead and increased my idle by about 160 to account for the low idle post cam install. Everything was Jake until I started it up this morning and I have an SES light again and although I haven't checked it, I'm guessing it is the P1015 code again. Does anyone know what this code is?
