Check engine codes

Hello,

In the diagrams down below I have included the diagnostic troubleshooting guide from the vehicle manufacturer for Direct Trouble Codes[DTC][s] P0171, P0174, and P0191. Please go through these guides and get back to us with what you find out.

Thanks,
Alex

If the fuel pump in this vehicle is original, replace it! Then retest. I say this with confidence because I have replaced so many at my dealership that when I get an escape with these codes that has the original fuel pump in it, the first step is to replace the pump before any other diagnostics are to be performed.
