I have a 2015 F350 super Duty 4x4 SRW, I have had this truck for 3 years low mileage and the engine like came on, and I had the code checked twice and both time came out with 0170. PCM problem (Fuel trim malfunction Bank 1) Has to do with the Fuel Air mixture or fuel issue. Talks about the MAF (Mass Air Flow Sensor) and I have taken it our and cleaned it with approved cleaning spray, and put it back in, and the light is still on.. Trucks runs great, like there is no problem. Can you reset the engine light? Has anyone had this issue before? Thank you for any info, Mark S.
