My 2014 Note HB showed a code P0003 from a Scangauge which seems to be related to Fuel Volume Regulator Control Circuit Low.

NO CEL comes on and the vehicle is running fine. I cleared the code and tested it the next day. Same code P0003 came up along with B2A00 and B2AAA, which I believe these two codes are communication settings. Is there something I should be concerned about and were on the engine do I look to find the Fuel Volume Regulator Control to check to see if there are any wires broken or eaten up from mice.
Yes.. mice... I had one eat through a sparkplug wire on my snowblower down to the metal.

If the car is still under warranty, take it back to the dealer and let them handle it.

Yes... That is one of my options but I am over the 60K mile mark. I'll scan it again at Autozone this week and see if they see the same code.

Thanks

Had it checked at Autozone no codes came up. I did not expect to see one as the ECM is keeping things balanced, but the negative -7 LTFT is showing a flag

I did scan it with a Go Point phone scanner and noticed the LTFT was -7 STFT was +3 and never really went to zero
Oxygen sensor voltage .28 and came up to .55v and dropped with RMP Cat temp came up to 900F but dropped back down.

So I am seeing a Rich LTFT O2 is also showing Rich being at a low voltage,

I was questioning MAF sensor.... did not move at low RPM Will look at it at higher RPM. Side note, I have been using K&N air filter which might have caused the MAF to not respond. Is the MAF sensor a film or a wire?
Am I heading in the wrong direction?
