So ive started working on this black cat and im getting both bank MAF faults.
1. In many threads clear plastic vaccum hoses are mentioned can anyone give me a better idea of their location.
2. I checked intake seals they seem to be good.
3. I bought 2 sensors and replaced them both still faulting this leads me to believe its not the sensor itself.
4. Does anyone have the wiring diagram for the 09 xf sc

On a positive note i got aftermarket rims off a totaled xf and i am looking at exaust systems so everything is moving forward. Ill post pictures of the mounted rims tomorrow.
thanks for any help in advance jesse

 

Did you get this resolved? I am having the same issue.

 

When you say faulting are you just saying both banks are giving you the P071 and 074 codes? if so issue most likely the throttle body brake booster O-ring issue. do a search, common especially now at their age. I am having same issue...Same year.

 

What fault code are you getting
