ODB codes giving me troubles again

[Docta]

Ran the scan, and came back with 4 codes now.

DTC P0137 HO2S Circuit Low Voltage Bank 1 Sensor 2
DTC P0138 HO2S Circuit High Voltage Bank 1 Sensor 2

Seems very contradictory to me...

DTC P0140 HO2S Circuit Insufficient Activity Bank 1 Sensor 2

Those 3 are all from the post cat sensor right? Because I simply don't have that one in the car.

DTC P0153 HO2S Slow Response Bank 2 Sensor 1

And this one is the passenger side manifold right? I have a replacement just gotta make sure it's the right one. I don't understand the whole bank 1/2 sensor 1/2 system....

Any help?


(Genius self spelled OBD wrong....)

Sensor 2 is always the post cat sensor. remove the codes via HP tuners or put the sensor back. Bank 2 is the passenger side, bank 1 drivers. Slow response generaly means the sensor is going bad.

Had P0138 pop back up today, even though I have a simulator in there... have to check that out.

The trouble this time Is coming from P0650. Which from what I can tell, says the malfunction indicator light, is malfunctioning. Wtf. What even is... my SES light is broken?
