P0175 Ford Code - System Too Rich Bank 2
Quick Answer
With the Air/Fuel Mixture Ratio Self-Learning Control, the actual mixture ratio can be brought closely to the theoretical mixture ratio based on the mixture ratio feedback signal from the heated oxygen sensors 1. Common causes include Faulty front heated oxygen sensor, Ignition misfiring, Faulty fuel injectors. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Discuss the causes and fixes for P0175 Ford OBDII Code

my 2014 E-250 Van's check engine light keeps coming on. Codes read p0172 and p0175. Its been to the ford dealership 3 times. They clear codes and charge me and send me home. I took it to a local mechanic, he changed the mass air flow sensor, cleared codes.... 150 miles later lights back on, so I take it to another mechanic on recommendation. He replaces the thermostat.... 130 miles later lights back on.
-
Most of the times if you have the P0172 and P0175 codes, the problem is the Mass Air Flow (MAF) sensor. Did you use a new factory sensor?
Other than the MAF I have never seen any other problem triggering both codes.
