Before you replace parts

Read all stored codes and freeze-frame data. Fix misfire, fuel or sensor codes before chasing emissions codes.
Check the simple things first: connectors, vacuum hoses, fluid levels and the gas cap.
Clear the code only after a repair, then confirm it stays off after a few drives.
Check your VIN for recalls and service bulletins.

Safety / mechanic note

Verify with a mechanic if you notice drivability changes, warning lights or overheating. A code points to a circuit or system, not always a specific part.
