car failed mot on high immisions , skoda felicia 13mpi , just scanned it and its giving 3 faults 00525 o2 sensor voltage low /. then 17978 contol module locked ? then 01247 ev ap canister purge regulator valver -n80 ? so me thinks new lambada sensor . but the other 2 faults i dont know what they are i think one is the charcoal canister if so is it a new one or can it be cleaned out i have now cleared the faults with the scanner . so do you think i may just get away fitting new o2 probe ? thank you sean

ok ordered a new sensor , the fault thats locked is immobilizer i now know what that is , the other fault i have been told will not effect the emissions test ?
