My CEL came on with the following codes:

17831 - secondary air injection system Bank 1 P1423 - 002 Insufficient Flow
17819 - secondary air injection system, Bank 2 P1411 - 002 Insufficient Flow

My tech basically told me that the wiring harness is falling apart and probably needs replacing. I asked him if he could run an overlay and see if CEL goes away. Anyone replaced wiring harness in these cars?
