Possible causes p1131...> - Faulty Upstream Oxygen Sensor Bank 1 - Fuel pressure high or low - MAF sensor dirty/defective - Vacuum leak on engine - Leaking fuel injector or fuel pressure regulator - Faulty Powertrain Control Module (PCM) Tech notes Though the Oxygen (O2) sensor, the Engine Control Module (ECM) has detected a lean system, which means that there is either not enough fuel or and excessive amount of air in the system. Start by checking for vacuum leaks. When is the code detected? When an HO2S sensor indicates lean at the end of a test, the system is trying to correct for an over-lean condition. The code is set when the fuel control system no longer detects switching for a calibrated amount of time. Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light) P1131 Ford Description The Heated Oxygen Sensor (HO2S) Monitor is an on-board strategy designed to monitor the HO2S sensors for a malfunction or deterioration that can affect emissions. Under specific conditions, the fuel control or upstream HO2S sensors are checked for proper output voltage and response rate (the time it takes to switch from lean to rich or rich to lean). Downstream HO2S sensors used for Catalyst Monitor are also monitored for proper output voltage. Input is required from the Engine Coolant Temperature (ECT) or Cylinder Head Temperature (CHT), Inlet Air Temperature (IAT), Mass Air Flow (MAF), Throttle Position (TP) and Crankshaft Position (CKP) sensors to activate the HO2S Monitor. The Fuel System Monitor and Misfire Detection Monitor must also have completed successfully before the HO2S Monitor is enabled.

I would start by taking the first 02 sensor out and having it checked at Auto Zone. Replace as necessary. A code will still show up until it is cleared by a scanner.
