Error Code P0240 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

FishirOne · 09-14-2014, 09:30 AM

Hey guys, I have a 2013 Camaro 2SS.
I have about 14k km on it.
Recently I've been getting a check engine light. When I went to my local maintenance shop, They told me it's got to do with the Carbon Dioxide Module thing which reads the O2 and Carbon emission.
He cleared the code and told me not to worry about it. Now it's back and I just want to know what exactly it is and if their is a quick solution to this problem rather than taking it back to the dealer.

Thanks for suggestions!

There are a host of things that can cause a P0240 code. O2 sensor/s, cat, ignition fault, fuel/air mix, yada yada yada...Good luck... Yea, best to just let the dealer track it down.

There's no such code as P0240 also there nothing called a Carbon Dioxide Module.

Well, there actually is a P0240 code ( P0240 Turbo/Super Charger Boost Sensor "B" Circuit Range/Performance )

I mistook his post for a P0420 code and had the numbers transposed when I read it. Maybe that's the code the OP is getting. If not, I have no clue. P0420 code description is ( Catalyst System Efficiency Below Threshold (Bank 1)

I looked up that code in the 13 Camaro Service manual and it doesn't list that code (P0240).

Just install some long tube headers and hi flo cats, problem solved.

Maybe an outdated code then. Here's where I found it.

Maybe you mean P0420 Cat efficiency?
