bank 1 on front wheel drive car is the side next to the radiator or front of the car,sensor 1 is the first sensor you see on that exhaust manifold

bank 1 sensor 1 lean code. Check vacuum lines first. Could be egr leak also. Most vacuum lines run on the back side of the engine on these. Most common fail is the PCV 90 degree elbow. On the passenger side.

Possible causes
- Faulty O2 Sensor Bank 1 Sensor 1
- O2 Sensor Bank 1 Sensor 1 harness is open or shorted
- O2 Sensor Bank 1 Sensor 1 circuit poor electrical connection

P0442 FORD - Evaporative Emission System Leak Detected Small Leak

Possible causes- Missing or loose fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- EVAP canister or fuel tank leaks
- EVAP system hose leaking
- Fuel tank leaking
P0136 - O2 Sensor Circuit Malfunction Bank 1 Sensor 2
Possible causes- Rear Heated Oxygen Sensor Bank 1 harness is open or shorted
- Rear Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Faulty Rear Heated Oxygen Sensor Bank 1
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks

P0141 FORD - O2 Heater Circuit Bank 1 Sensor 2

Possible causes- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit fuse
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
- Faulty Engine Control Module (ECM)

P1131 is "Lack of H02S-1,1 Switch, Sensor indicates lean" I'd say you've got a bad Heated Oxygen Sensor at Bank 1, Sensor 1.

Hello
Bank one is the engine cylinder bank near the engine firewall (see diagram). The bank one sensor one is the Oxygen sensor (O2) located in the exhaust pipe just of the engine cylinder bank at rear and before the Catalytic Converters.

This code is the circuit malfunction for the oxygen sensor bank 1 sensor 2. This means that the engine computer is not seeing the sensor. It may need an new sensor, have a wire between the sensor and the computer that has shorted out, or just be unplugged. Here is a link to a trouble code dictionary.

the o2 sensors are located on the manifold and exhaust pipes under the car

P1131 bank 1 indicates the fuel/air ratio is correcting rich for an overly lean condition.
Diagnostic Trouble Codes (DTCs) P0133 and P0153 indicates the response rate of the upstream HO2S(s) is below some calibrated window. The test measures the HO2S amplitude and output frequency. This is accomplished by superimposing a 1.5 to 2.5 Hz square wave over Lambse. The HO2S switching is monitored during this time to see if the calibration limit is met. P0133 is also bank 1.
Although these codes could be caused by several things such as vacuum leaks,fuel contamination,exhaust leaks,miss-fires,etc. Since it is localized on only bank one I would replace that front(upper in the exhaust to back cylinder head) 02 sensor and see if that did not correct my concern.
