I have a code PO174 my car is not getting enough fuel in bank 2 system how do I fix it

Question

I have a Ford Taurus SES 3.0 and I want to know if replacing my fuel pump will stop the error codes PO174 and PO171 and P1237

Answer 1

HI there,

It's impossible to be 100% sure without testing, however the lean fuel mixture codes can be a result of low fuel pressure and the P1237 code is for the secondary fuel pump circuit. Without measuring the fuel pressure it's difficult to be 100% with the answer.
