i pulled up the on my scan tool because i just changed the exhaust and haven't bought the o2 sensor simulator yet and instead of the p2020 or w/e code it came out to be a B2AAA code. does any body know what that code means?

 

I have no idea what that means, but I found someone that had a similar problem, hope this helps

DTC's that start with a B are body codes. I have never seen a DTC that is Alpha, Number, Alpha, Alpha, Alpha. Every code I've seen in the various on line databases is a letter followed by 4 numbers. B2AAA does not exist in those databases.

Any chance this was just a glitch in scanning codes? Did you try it more than once?

 

no i only tried it once. thats what i was thinking that it could be a fluke. the light is off now and i will check again if it comes back on but hopefully it wont
