P0451, P0451, P0453 Fix?
 

Have a 2013 FRS, when CEL came on for P0451 and P0453. Checked gas cap and drove, then traction off light came on (then P0441). Tried to clear codes but could only clear P0441. Disconnected battery (>4hours) to reset computer but still did not clear the codes. High idle after that.



Thoughts on fix/issue?


If mechanic, anyone have one near the Fairfax, VA area?

That's odd that you could only clear the one code... Whats scanner are you using? I found a nice little EVAP diagram link from @Tcoat on another thread that might be of use.

Is your car modified? How many miles?

Did you check the fuel cap for a good seal? Is the gasket/o-ring failed, shrunk, etc? Is there an uneven surface leading to a leak?

Check for broken or loose hoses at the EVAP solenoid.

Just using a actron pocket scanner, not modified. And I actually replaced the gas cap with a new OEM. Haven't found anything loose either. Only 35k miles
