i have three codes what do they mean?

Question

I HAVE THREE CODE ON 05 COBOLT P0455, P2135, P1681 CAN SOMEONE PLEASE TELL ME IF THEY HAVE HAD THESE AND WHAT THE FIX IS

Answer 1

P2135 Throttle position sensor 1-2 correlation

P0455 Evaporative system (Large leak detected)

P1681 Internal microprocessor integrity condition.

The main concern is P1681, for this code condition it requires a reprogram of the ECM or even a replacement of the ECM.
