Dealer pulled code P0450, what could be the problem. Dealer did nothing except removed code and flashed PCM again. Is there any new PCM because dealer said no CEL after flash with new PCM. Is this code P0450 serious problem ?

BTW, where is the ODBII connector? I have ODBII reader, I could have clear the code myself instead paying 75 bucks for reading the code.

 

under the steering wheel, you will see a little computer type connector, thats it.

 

Chetrickerman, your are right. I found the ODBII connector. Thank you.

 

There is an OBD code database here, http://autorepair.about.com/od/obdco..._1996_year.htm
Not all codes are relevant to the RX-8 but your P0450 is "Evaporative Emission Control System Pressure Sensor Malfunction" I assume your garage fixed this now and all should be well.
