CEL p1110 and p1090 Help
Hi folks, I'm new to this forum and hoping for a little guidance from Porsche lovers like myself. CEL light came on the other day, hooked up the Durametric and got a p1110 and p1090. p1110 is 02 sensor heating circuit, bank2 - sensor 2 short+ b+.
p1090 is (I think) HFM electrical fault.
The p1090 seems to point to a MAF sensor and the p1110 seems to point to a O2 sensor.
My question is: What one should I try and replace or test first? Can the MAF cause the O2 to trigger or vice versa. If anyone has any other ideas/opinions/experience with this it would really be appreciated.
I've had no "noticeable" loss of power but after looking this up.... I might be loosing power. lol
