(2015 2500HD 6.0 with 50K) Started with 3 codes (P0138 Bank 1 Sensor 2 Circuit High, P013A Bank 1 Sensor 2 Slow Response, and P2271 Bank 1 Sensor 2 Stuck rich)  Replace driver side Sensor 2 on Sunday with new Bosch sensor. Then Monday night CEL back (tried to remote start) but just getting P0138 code now.  Can Sensor 1 cause sensor 2 to get a bad reading?  My thoughts are to swap Bank 1 Sensor 1 with Bank 2 Sensor 1 to see what happens instead of throwing money at buying parts.  Thoughts?  Check fuses?  I have a Superchips code reader so at least I can read and clear the codes myself (although that damn one keeps coming right back on)

 

Thanks
