Hi there,
Let me break it down. The trouble code P0420 is triggered when the on-board computer detects that the bank 1 of the catalytic converter is underperforming/faulty. Click this link for more details from our CarParts.com blog.
The code P061A, indicates “Internal Control Module Torque Performance.” It is logged by the PCM when the measured engine torque value goes past the maximum allowable engine torque value. Click this link for more details from our CarParts.com blog.
And the code P2681, can be defined as "Engine Coolant Bypass Valve Control Circuit/Open." This error code would indicate that an error has been detected in the engine coolant bypass valve (due to leaks or internal electronic failure) control circuit by the powertrain control module. The possible parts that are also affected are the coolant temperature sensor, the ECM, or PCM. I hope this helps!
