O2 sensor is the lambda/oxagen sensor/s, both of which are screwd into the exhaust system, the up stream one is the engine side of the CAT,

sometimes removing them and give them a good blast out with carb cleaner will sort them out, if not it/they need replaceing

try this company for new ones

the front/upstream one will be somewere between the exhaust manifold and the CAT, and the downstream one will be rear of the CAT,

Doubt its the sensors, The Canister purge solenoid & the oxygen sensor heater elements are bot powered up from the same section of the double injection relay share a live feed which is too much of a coincidence, It goes via fuse 34 of the under bonnet fusebox so deffo worth a check first.
