Hello all. I was wondering if anyone else has experienced both P171 and P174 on their Super charged Jag. I highly doubt both MAF sensors could go bad simultaneously and they are not cheap to replace. Any help would be appreciated. Thanks, Jim

If you haven't done so already you should add your car details to your signature to help others to help you.

 

Welcome to the forum.

Lean on both banks is often caused by a vacuum leak somewhere between the MAF's and the throttle body, lots & lots & lots of posts here on the forum talking about this issue. P0171 & P0174.

Do a general search as the engine in your car is the same as the S-Type R, X350, and the early XF's. Rubber vacuum hoses do perish over time, or maybe even one has been disconnected somehow.

EDIT

Also check the plastic intake tubes for splits at the welded seams.

 

welcome

 

I hope my car and bio are visible now!
