I recently install the Vortech V3 Supercharger, and the SES light came on.
P0037 - HO2 Sensor heater Control Circuit Low (Sensor 2, Bank 1)
P1283 - Faulty Air fuel ratio (Sensor 1, Bank 2)
I'm trying to buy a new O2 sensor and see if this will fix the problem, but not sure where this sensor locate at (Sensor 2, Bank 1)(Sensor 1, Bank 2).
I know it on my test pipe, but not sure what sensor 1, 2 and Bank mean...
Help

p1283 sensor 1 bank 2 - drivers side sensor pre cat

sensor 2 bank 1- is the cat sensor passenger side.

You should do some logging of your A/f ratio see whats going on first before dumping money on sensors and search there are stickys on the codes.

I notice my A/F is a little wired, it used to be at around 14.5 at idle, but now it at 13.6 at idle, not sure if it because of the weather getting cold or the sensor is bad =(

I'm trying to buy the sensor and there is "Downstream" "Upstream"........?
Is Upstream the A/F ratio sensor and Downstream is the O2 Sensor?

My bad, I think I wasn't specific. What you have to do is monitor the actual sensors voltages/readings and narrow down whats the cause of code p1283, which could be anything from an exhaust leak to vacuum leak to dirty/clogged injectors to a bad sensor.
It would also help if you could list the mods/tuning you have.

Correct.
