Check Engine Light
My check engine light comes on for a few days at a time and then goes off again. I brought it to auto zone to get the code read and it says a critical HVAC error. Then it said something about ATC??? Does anyone know what that means? The light has been off for about a week and I have had zero issues while driving. I was curious if anyone else has seen this code?

Do you have the code number itself?

Ken I just found the receipt from auto zone and here is what it says: P2259 HVAC system is reporting a critical error- torque reduction requested Check ATC system for fault codes. To add to all this, the computer thought that it was a Chrysler??? |
A lot of the codes are not universal, and vary from one make to another. According to the list of codes for the RX-8 (they're in a sticky at the top of one of these fora) that code is:
P2259 AIR solenoid valve control circuit low ON 2 CCM and according to the shop manual has something to do with the secondary air injection (AIR)system. There's a great pdf of the shop manual at http://www.hi-impact.org/ryang/modif...8_manuals.html and there's a page on this code and system in 04_EngineControl. The problem could be anything from a bad connection to a bad PCM. Looking this much up pretty much exhausts my knowledge. Hopefully some of the more knowledgable members here can guide you further.

Thanks Ken, I appreciate the help!

Hi everyone.
so my check engine light came on recently and i took my 8 to th auto shop for an ODB scan. and the codes PO456 and PO442 came up. the guy at the shop told me it was a problem with the "canister purge valve". but when i went home and reseached it i noticed that many others got the same code and its a common issue with the gas cap not being tight (a glitch). i also heard mazda fixes this glitch for free. but has anyone else had a canister purge valve problem? i think the guy was bullshitting just trying to grt me to pay for something, because the car runs great and nothing sketchy is going on when i drive it. thanks |
Could be as simple as the loose gascap, you don't have a location or the year of your car - has it been reflashed at the dealers?
The fix is a change to the computer program, but most cars in the US got it long ago.... |
