Gang....some of you know me from my long ordeal on lean codes on my 05 3.0 s type, which I finally resolved with your help. But oh no....now the 09 XF 4.2 I recently acquired threw mil and 0174. Yikes...I read the obd and saw the 0174 as pending yet the mil on? No other codes. I looked at the fuel trims both stft and ltft and they all look good. Nothing is reading high, as I would have suspected and the car is driving great. So......although I am more than familiar with all the conditions that can cause 0174, ny thoughts on why I would get 0174 with all fuel trims ok?
Side issue.....the car also displaying tire pressure monitor system fault and it won't go away. All tire pressures are good. I checked the 5a fuse for the tpms in the trunk fuse box and it is good. What's up?
