MAF Sensor / OBD2 codes for Vantage

[Sirius]

Hi All,

So the first hiccup today, driving home the CEL came on and Emissions System Service Required popped up.

I've got a code reader and also done searches on here and on Google.

The codes I've got are P010A and P010F which I believe are related to one of the MAF sensors (the B circuit?) and mismatched readings between the two sensors (the F code).

Does anyone have the OBD2 Manual for the V8 Vantage - a few posts seem to suggest the code relates to one or the other sensors but I can't establish which.

The sensors don't appear to be too expensive and a short job to replace so I don't want to replace both unless necessary.

Thanks

The obd document does not say which is bank a or b. It may be worth disconnecting one and identifying the bank the from the fault code generated from the disconnection?

Sorry, deleted my comment. I read oxygen sensor not MAF!

(Although, to repeat what I said - bank 1 is drivers side (RHD UK car) so I guess that's probably also bank a.

A common cause of the "MAF sensor correlation" warning is that there's a mismatch in air flow going through each side. This can be caused by an air box cover not being properly installed (cover not aligned, or the cover gasket being pinched), or a crack in an air box, or a loose intake filter.

It could also be due to one/both of the MAF sensors going bad, being damaged, needing to be cleaned/replaced, or something along those lines. My grey V8V had K&N intake filters on it when I bought it, installed by the original owner. Both MAF sensors had to be replaced because of them.

Here's a write-up for changing them.

For some reason the video isn't embedding in the write up, so here's that:

Thanks - I found your write-up and video last night. Really helpful.

I'll hopefully get a chance to have a look at this in the next few days.
