I scand mine on two different occasion and the fault code 16486 came up as well, after resting it felt better. I guess the MAF is on it's last leg!

the other two sound like your lambda sensors. and it seems you have two of them.

I would look into reseting all of it then scanning it in a 100 miles, then you can be sure if they are all at fault.

the lambda fault is with one sensor id say, bank one is the pre-cat sensor also. If you clear it and it immediately reappears you need a new one most lightly, although its worth checking the wiring and connection plug first. I dont think a dodgy maf would trigger the lambda faults but could be wrong

01314 - clicky

013 - Check DTC Memory - According to wiki Ross-Tech, this message is thrown up as a note referring to relevant fault codes stored in another control module. Maybe need to scan another memory block ?? I dunno.

16486 - clicky

Hope this helps
