I have a p1516 code on my 2003 suburban and am trying to figure out how to fix it

Mechanic's Assistant: Okay, I'll connect you to the mechanic to go over that information regarding your Chevrolet Suburban. Before I do, is there anything else you want him to know?

P1516 usually means the throttle body assembly is failing which will cause it to go into reduced power mode. The other two codes usually mean the bank 1 sensor 1 oxygen sensor is failing. I'd start by checking connector and wires near connector on throttle body if good replace throttle body and I'd also replace the bank 1 sensor 1 oxygen sensor. Let me know if you have questions, thanks.
