If you've been notified of an emissions system issue on your 2017 Honda Civic, you'll need to check the diagnostic trouble code (DTC) to identify the problem. The common one you might see is the P0420 code, which points to a fuel injector problem, although there are other emission issues that could cause this error message. Surprisingly, a loose gas cap can also trigger this notification if you don't tighten it securely after refueling. It may sound alarming, but it's a simple fix in that situation.

I've had to replace the purge valve two times already, and now the check engine light is back on. I'm worried about the repair costs. My car has already clocked 117,000 kilometers. It's going back in today to get checked, but it seems like they're unsure about the cause of the issue.
