DTC FAULT P0155 AIR FUEL RATIO A/F SENSOR BANK 2 (B2) SENSOR 1 . Inspect lambda sensor on bank2. Bank 2 is the front of your engine. Sensor 1 should be first sensor located in front of the engine(upstream).

Possible cause

1) heater element could be bad.
2) circuit problem

Solution: check resistance value using a multimeter. If you have a a scan tool you can check the sensor reading via actual values

P0135 Acura O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 1

Sensor is located at the firewall (rear of the engine)

Carry same approach listed above to have it fixed

Lastly p2279: intake air Leak: have all vacuum hose inspected and fix accordingly. I would advise you have this code fixed first because the amount of intake air going to the engine has been altered so therefore lambda sensors would pick a false reading as against the norm air fuel ratio(14.7: 1). Have that intake air hose changed

N.B: Air fuel sensor might just check out fine but might come out as a fault code if you have this intake air leak

I hope this helps you

The car has really been abused..
If I was in your shoes, I will go this way

- Replace the rubber mended with tape( air Intake tube )
- check around engine bay for any sensor not connected.. If any, connect it.
- check for any other torn rubber hose in the engine bay
- Clear the codes
- Drive around and see what codes come up
- Then attend to any code the ECU throws
