Heated O2 sensor

There is 1 code for a "Very small vaccum leak", besides that all other 9 codes are the O2 sensor. Could that small vaccum leak really set off all those codes for the sensor? Thank you for the advice, I'll look into that first before I go out and pay $200 for a single O2 sensor, which only Ford carries because it's too new lol.

yes it could,my F150 threw 9 codes a few years ago.none of them were vacuum related.i found it by the sound of the Hissing noise.this was from a code reader like Autozone reads their codes with.one little piece of vacuum hose(9)codes,i just got lucky and found it by sound.i have seen Autozone read codes for folks and punch that code in their computer system,tell customers possible causes,like MAF sensor (could be bad)and the customer would say,go ahead and give me one,the old one has been on the car for 5 years.well $200..00 later check engine light is still on,and the parts house did their job,they sold you a part,now you are scratching head! todays vehicles are very complicated to diagnose unless a mechanic has the proper scan tool with live data verses a code reader,you really would be guessing/throwing money/parts at it!No Warranty on your car?
