Question

I have a problem with code P0174 code on my 2001 Ford Windstar 3.8L

Answer 1

Hi there,

The code P0174 indicates a lean fuel mixture on bank 2. This can be caused by a few things, first and most common would be a vacuum leak along the intake on that side of the engine.Other possible issues would be a faulty O2 sensor or some type of fuel issue. Sometimes a leaking exhaust will cause the code as well.
