P0172 and P0175 on 2014 Limited

[juliomad]

I am getting these codes for my expedition. I tried using the Zurich ZR13 to help with this, what exactly should I be looking for?

I would start with the basics like fuel pressure, vacuum leak, O2 sensors, MAF, fuel injectors (w/ noid light) and the tstat.

Here’s a possible cause, read this:

Looks like I am tracking this down, my wife’s 2017 just gave me a P0172 and P0175. I found the valve on top of the motor, disconnected the line at the back as the other lines feed into intake—so I assumed those are vacuum source and the one at the back is to the canister. With the wire connector disconnected, there isn’t any suction, but connected there is constant suction. So I believe the purge valve is working on ours. Need to find the next likely culprit—-any thoughts?

All codes are clear, but I am still getting a misfire somewhere but no codes. I don't know if the Zurich ZR13 will read individual cylinder misfires. At least I have not been able to find.
