P171 = is it the MAF sensor ?
Hi All, After cleaning my MAF a P171 code came back. MAF g/s reading on my 2008 S80 T6 are:
at idle 3.2 at 2500 RPM 12.4 Snap Throttle test the G/S goes to 40+ The ST Fuel Trim at idle is 14, 3-10 at 2500 RPMs, and Zero with a Snap The LT Fuel Trim is 27 at idle, Zero to negative 3 at 2500 RMPs, and Negative 2 with a snap Are the above value ok? I am trying to figure out if i have a Fuel issue or Air (Volume, MAF...) issue? Thanks in advance, G08 |
