2005 SiG P0134/P0139

So I'm getting the engine light intermittenly on my 2005 SiG, I did scan to see what's up and it's throwing 2 Codes. P0134 02 Circuit No Activity Detected ( Bank1, Sensor1) and P0139 02 Circuit Slow Response ( Bank 1, Sensor 2). From what I'm seeing it could be -
Possible causes Faulty Air/Fuel Ratio Sensor Bank 1 Air/Fuel Ratio Sensor Bank 1 harness is open or shorted Air/Fuel Ratio Sensor Bank 1 circuit poor electrical connection Inappropriate fuel pressure Faulty fuel injectors Intake air leaks may be faulty Exhaust gas leaks. It's also throwing out a P0139 02 Circuit Slow Response (Bank 1, Sensor 2)Possible causes Faulty Rear Heated Oxygen Sensor Bank 1 Rear Heated Oxygen Sensor Bank 1 harness is open or shorted Rear Heated Oxygen Sensor Bank 1 circuit poor electrical connection Inappropriate fuel pressure Faulty fuel injectors Intake air leaks may be faulty Exhaust gas leaks. I started to think back and it wasn't long after I had to replace my Caty so I'm going to get it up where I can get a good look and check the wires first. If I have to replace the sensor is it a O2 or a Fuel/Air as there a big difference in price, also if it's a O2 can I use the one out of a 03 Civic non V-Tec? Any thoughts ezone?

You need to use the a/f sensor, and you need to buy the OEM brand. (Denso or ntk)
