When did this happen? All of the sudden? After any maintenance or upgrades?
FWIW, Just found this in my service manual...
"H40 DTCs P1131, P1132, P1151, P1152, P2195, P2196, P2197 AND P2198: UPSTREAM HO2S NOT SWITCHING.
Note: It is necessary to address all Continuous Memory Ignition and Misfire DTCs, if received during Continuous Memory testing, before addressing any KOER HO2S DTCs.
DTC/HO2S Reference List:
HO2S-11 = DTCs P1131, P1132, P2195 and P2196
HO2S-21 = DTCs P1151, P1152, P2197 and P2198
Check intake air system for leaks, obstructions and damage.
Check air cleaner element, air cleaner housing for blockage.
Verify integrity of the PCV system.
Check for vacuum leaks. "
From there, it has you look at the MAF sensor, baro, long ft1, long ft2 and maf v via a scanner... do you have one of those?
