Here are the possible causes for the PO171 and PO174 codes:

  • Base engine mechanical problem affecting one or more cylinders
  • Check for air leaks after the MAF sensor
  • Check for air leaks in the Air Induction system (e.g., in the intake manifold)
  • Check for air leaks in the EGR system and in its related hoses and/or valve
  • Check for air leaks in the PCV system and in its related hoses and/or valve
  • Fuel control sensor is out of calibration (e.g., ECT, IAT or MAP)
  • Fuel delivery system supplying too little fuel during cruise or idle periods (e.g., faulty fuel pump or dirty, restricted fuel filter)
  • Fuel injector (one or more) dirty or pressure regulator has failed
  • HO2S has failed (it may be contaminated with fuel, silicone or water)
  • Vehicle driven low on fuel or until it ran completely out of fuel

Please let me know if this information is helpful. Positive feedback is appreciated. Thank You!

  • In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
  • Inspect all vacuum and PCV hoses, replace if necessary
  • Check for a dirty fuel filter and proper fuel pressure

    You did not state the symptoms you're getting(problems) . The lean codes are usually caused by either a bad vacuum leak or the Coils going bad,causing a miss.

    P0171 & P0174 are lean codes.this can be cause by a vacuum leak. One of the symptoms is a ruff idle when cold.

    You can listen for it or you can have it smoke checked by a shop. Most common causes are intake plenum gaskets and rotted PVC hoses.

    2004 mercury montery sputters when in idle , went to autozone got codes p2197,p2195,p0171,and p0174 have changed fuel filter and still continues.

    Most likely a vacuum leak effecting the O2 Sensors

    That is your 4 codes.

    Have the Evap System checked also, for leaks

    Fuel Filter--filters fuel,doesn't fix anything
