Ford Fiesta ST Air leak issue. p2279 p006a

[stedaley]

Getting OBD issues of P2279 and P006A on my 2014 ST3

Had the car in a garage and they can find the issue.

Changed MAF sensor. Had a smoke test on the Air system / recirc. Recirc rocker cover has been changed to fix the power issue i had as well. (130hp was being produced.)

Any other ideas of what to try before taking it back into someone else?

Regards

Hi. Did you manage to figure out the issue?

I am having the same problem.

My P2279 P006a turned out to be a fault with the throttle body.

Eventually after trying many things I swapped the throttle body with a spare I had on a wrecker engine.

So air leak (or as perceived by the PCM) was on the intake side.
