ok so i just had my check engine light checked today just couple of minutes ago at autozone. what i got back was these two codes (P2259 and P2010) i searched up on the rx8 forum about these two codes and i can only find P2259 and i am thinking about doing this diy from jon316g testing out the solenoid with some friends (maybe). And for the other code i cant seem to find it i also used this thread from zoom44 (https://www.rx8club.com/series-i-tech-garage-22/rx-8-technical-info-cel-codes-pcm-pin-list-collision-guide-26291/) but i cant find the code...
what i got back from autozone is this:
definition
variable tumble control system (VTCS)-solenoid
valve circuit high input
prabable cause
-open or short circuit condition
-poor electrical connection
-Failed VTC solenoid valve
these was for the P2010 one and for P2259 the autozone guy dont know what it is, he just wrote that code on the print out paper and told me to go talk to mazda

04 rx8 gt mt with 65749 miles on it
