What to check first on this engine

These come from how this specific engine fails, not from a generic code list.

1

Start at the fuel cap, not the canister

The filler neck and cap seal are the usual suspects on this generation. Tighten the cap until it clicks, clear the code, and drive a full tank before ordering any part.
2

Confirm the EVAP monitor actually ran

The test needs a cold soak and a partial tank. A readiness screen that still shows EVAP as incomplete means the code has not been retested yet, not that the repair failed.
3

Smoke test before replacing a canister

A canister runs several times the price of a cap or a hose. Ask to see the smoke plume rather than a description of it.

Vehicle-specific NHTSA complaint counts, model-specific labor times, and OEM part numbers are not on this page. Those numbers need a source we can cite, and the ODI complaint data has not been ingested for this build. We left the fields out rather than print a figure we cannot back up.
