2006 xc70 mass air flow sensor

Post by jasontindal » Sat Nov 09, 2019 1:40 pm

HELP - I have a 2006 xc70 and it is giving code P0101 and P0170 (fuel trim bank 1) and P0103. I have installed a new bosch MAF sensor, still no fix. I read to check the power supply on the connection and best I can tell is to pin # 4 and I am getting about 4.5 to 5 volts. Internet said that # 3 should be the power supply and it is zero volts. I have checked the 15 amp fuse on # 12 in the fuse box under the hood and it is definitely good. What do I do now?
