Had P0497 (Evaporative Emission System Low Purge Flow) and P145C (DTC not defined - something along those lines) pop up a few days ago and they seem to not go away.
Info on car: 2015 Civic Si, all stock.
I did have the "tighten gas cap" message come up with a code (forgot what it was). Purchased a brand new OEM gas cap from Honda, installed, and message went away. The very next day, P0497 and P145C came on. Read a bunch of stuff online and some people suggested changing the purge control solenoid. I purchased a brand new one from Honda, installed it today, cleared the codes, and my CEL came back on. I told my eTuner about the problem, and he suggested to check the vacuum lines. I checked the vacuum lines to and away from the purge control solenoid and there are no crimps.
Also, I know with newer cars, the ECU stores permanent codes and cleared after the problem is fixed and car goes thru a set cycle. When I cleared the codes, all the pending and confirmed codes are erased, but the permanent ones are still there. Drove my car for a bit, and I got the pending and confirmed codes back in my system (a total of 2 different codes, but 3 times: so 6 error codes).
Anyone else have any suggestions? Would like to get this thing fixed asap.
Thanks
