Help with CEL Codes!
Alright fellas. Hoping to get some help. - I got a CEL last night, car runs great. These are the codes that were read.
aaCatalyst efficiency monitor malfunction - bank 1. Probable cause:
aa1 - exhaust leak
aa2 - Check other service codes first
aa3 - faulty catalytic converter.
BTW: 2005 RX8 GT, 66k miles on it. Runs like a dream. A good dream that is. Averages 20 mpg.

wcs, that looks like he is just copying text results.
iMoto (any connection to the race team?), that code usually only throws when your cat has failed or you have installed a midpipe. It means the ECU is seeing that the cat isn't filtering down the emissions properly.
If you have a cat on, and you are in the US and within the 8yr 80,000 mile federal warranty, go get the cat replaced at a dealer.

No, the sensor failing gives other errors, with a few being possible. My 8 is throwing the code for the rear O2 sensor "heater circuit voltage too low", i.e., it's cooked from my MM tune exhaust heat when I had the BHR midpipe on for ~40,000 miles. I'm ignoring it, because that tune and pipe are about to go back on, and it would just cook yet another sensor.

Agreed. I just ignored the rest and focused on the text of the CEL, which does indeed match one of our CELs. I assumed the rest of the "aa" prefixed items were just search results that he pasted in, and whatever pasting method he used interpreted the leading bullet points as "aa".
