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

You can disconnect the negative cable of the battery for a couple of minutes (but you will lose radio settings and possibly others that the car will relearn), or you can go to an auto parts store such as Advance Auto or Pep Boys and they have a free scanner service to diagnose problems that should be able to reset the light. Mine does.
