will what I know through my experince is that a code of the o2 sensor will convert to 2097 if the problem have been running for a long time or if both of the readings before and after the cat are the same so if you have cleared the cat or you have the code for long time it might be the cause
- P0138 HO2S Circuit High Voltage Bank 1 Sensor 2
- P2097 or P2099 Post Catalyst Fuel Trim System High Limit
so it seams that you have a sensore problem since both of them at the same side
- why is that. if the post cat sensor is bad resulting to give a zero value to ECU then the one after it gives a higher value then both codes will appear the broken sensore and high limit
P0138 & P2097 codes on T&C
