Last week my car thew a Service Engine Soon light, I read the codes when I got home and it showed the following codes:
2C32 - DME: Lamda Control 2.
2C6B - DME: Oxygen sensor after catalytic converter: System check.
Update: It's now throwing this code as well:
2C28 - DME: Oxygen sensor 2 before catalytic converter. System update.

I'm not exactly sure what these are for, but I know it has something to do with my O2 sensors.

I cleared the code and the SES light didn't come back up but the 2C32 code was still being reported by the DME. However, today the SES light came back on and only the 2C32 code was reported. Any ideas of what could be causing this issue? The only mods done to the exhaust are VRSF cat-less downpipes which I've had for a few hundred miles.

My lambda codes including those were 95% fixed by putting new primary o2s in. Im sure i could 100% fix it and not ever seen them again with new secondarys aswell but considering i only get a code once in 6 months and then not again after clearing im not too worried.

This gives me hope - I've recently seen this code myself and want it gone.

After seeing this code for weeks on end and clearing it repeatedly I finally replaced my primary o2's and haven't seen the code return in almost 2 weeks! Thanks!
