The Final Thoughts
Some Honda Check Engine Light Problems
While there are thousands of diagnostic trouble codes, some are more common with specific vehicles than others. Common causes of the check engine light in Honda include:
- Loose or damaged gas cap. A loose gas cap can allow extra air into your fuel mixture. This can cause a number of trouble codes, like P0171 (System too lean) or EVAP system leak codes (P0455–P0457).
- Oxygen sensor. Honda oxygen sensors have a widespread reputation for losing efficiency and failing. P0420 is the most common oxygen sensor code in Hondas, but it can also trigger codes P0130-P0147.
- Spark plugs. Even good spark plugs only last between 60,000 and 100,000 miles. Most Hondas will outlast their spark plugs. Failing spark plugs cause misfires, which will at least trigger codes P0300-P0314, and often lead to other problems.
How to Reset Check Engine Light: Honda Accord
- Plug your OBD2 scanner into the OBD2 port in your car. This will be in the passenger area, within 3 feet of the steering wheel. In a Honda Accord, it’s usually under the steering wheel on the door side. The scanner should turn on once it’s plugged in.
- Follow your Honda OBDII scanner instructions for reading diagnostic trouble codes. Make sure you cycle through all the codes that come up.
- Press the “clear” button to erase the code. You may need to do this for each code that has triggered it.
- If the check engine light comes back on after you’ve done this, it means there’s a problem you should address. Read the codes again and identify the root of the problem. Once all necessary repairs are made, clearing the codes will deactivate the check engine light.
As you can see, the best OBD2 scanner for Honda depends mostly on the model year of your vehicle. Consider your budget and which systems you want access to. No matter which way you go, you’ll save yourself money at the mechanic by knowing exactly what’s wrong with your engine.
