P1131 on an Expedition is a mass air metering error, not to be confused with a mass air sensor. The engine control module cannot see the bank one sensor one O2 sensor switch from lean to rich. Basically, the sensor is either bad or the wiring has a fault or short somewhere between there and the ECM.
