P0106/P0441 codes
 

Hi gents; My boy's 2017 turbo 4 cylinder is showing the manifold pressure P0106 code and the horrible P0441 emissions code. I've replaced the turbo pressure sensor and cleaned the MAF sensor that's on the intake to no avail. As for the emissions code, I hate to go there because there could b several problems. However, I did resolve my other boy's old Taurus's emissions code by taking out the gas tank and finding a split vacuum hose...ugg. Before I get all dirty and sore, have any of you gents tackled these codes? Thanks my friends for any help you can give me!

I had a P0441 popped up on an S70 I had. Turned out to be a bum gas gap.
that was after an oxygen sensor, purge valve and some vacuum lines were replaced.

the P0106 is saying the MAP sensor input is out of the acceptable range. Some models like my Gen 1 S40 actually have two MAP sensors... The P0441 is an evap system issue (the evap system recovers gas vapors from the fuel system so its for emissions and won't impact driveability). Can be caused by a wonky purge valve (on my S40 its up front on the drivers side of the radiator area), or can be caused by a gas cap as noted or a vacuum line. There's a vaccuum line that runs from the front all the way to the charcoal cannister so a smoke tester may be needed if that tears.

What I'd do is clear the codes and see what returns then go from there. Is the car running ok?
