I dont have any help, but my car just started throwing the 1283 code yesterday after 2000 miles after the supercharger install. If I had to guess its probly a rich condition because of the gas smell on my car. Ill do some research and get back to ya

Thanks dude, am tuned with Osiris but the guy who did it is out of town. I will also let you know how to fix it. I believe we are running rich.

Ok, still no update but man this forum is lacking in info. Just guess guys on here are not into pursueing there own fixes. Anyways I still havent done any trouble shooting, but I think its got to be a fouled sensor. People are getting the similiar code on the passenger side bank. My car is extremely rich. I am going to install my wideband hopefully this weekend, and will confirm. Then we will know its a tuning issue. Its throwing a code for a lean condition but I highly doubt its lean. Ill be back next week.

If you don't provide enough information, you cannot expect to get any useful responses. Should we assume the OP has a stock car and is getting these codes? If so, just take it to the dealer and get it fixed - no response is necessary.

I agree more info is needed, but you have a pretty good concept of whats going on from other threads. He has a reported lean condition on both banks. I think most of these code issues are in FI applications.

Could be an exhaust leak since the ECU thinks your lean but you're smelling fuel. Could also be clogged cats.

It could be an exhaust leak because i know i have one. I think its my Y pipe that needs a new gasket and a bit of welding in it.

You answered your own question.

i just got done dealing with p1273 and 1283 errors...

i had to replace my o2 sensor(bank 1 sensor 1) and that was the end of it.

this is probably the solution to your problem.. aside from your exhaust leak..(get that fixed first obviously).. then try replacing the sensor if u still have SES light on

did u replace it your self? im having a hard time getting to my primary o2 sensors : / ....

Ok so I got the P1273 code... Quick question, How many O2 sensors are there (2,4) and where are they (cat ) ? Also since this code is for an air Fuel sensor Heater Bank 1 then where is that located? Any Diagrams would be nice. Thanks!

there are 4

if u get ur car on a lift u can see 2 that are connected to your cats and 2 that connect to your exhaust manifold

I searched on here and cant seem to find an answer for this problem. I just threw both these codes again. I have monitored my loggs and I am running so rich I dont see anywhere that the ecu had to add much fuel to correct my AFR's. Infact through many logs my ecu has been pulling a ton fuel just to remain stoic.

Figured I would post on this again. I still recieve this code weekly. Theres a brief period going into boost (sometimes) that the ecu adds fuel. However its well within the range of the stock ecu's compensation. So the AF's are in check. I have many logs and I am not seeing this lean shift on both banks. Depending on the week some times I get 1273 and sometime 1283 and sometimes both. I dont know what is causing this but everything seems to be in check. I am thinking about having a reflash in order to remove these codes.

Some one chime in and tell us the secrect to these B/S codes.
