When I reset the codes, 0017 would come back within a minute of running the engine. 0171 would show up after driving the vehicle for 30-40 miles. I first focused on 0017. I've changed the actuator solenoid ( 3 times), camshaft position sensor, crankshaft sensor. A code P0171 may mean that one or more of the following has happened: The MAF (Mass Air Flow) Sensor is dirty or faulty Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry. .
