I have a 2000 Honda Odyssey with a 3.5 liter V-Tec engine. The check engine light came on. I used an OBD2 scanner tool and retrieved code P1456, which my service manual shows as "EVAP System Leak Detected (Fuel Tank)." I have since replaced the fuel cap, making sure to twist it 3 or 4 clicks, and then erased the code. The check engine light came on during the next couple of trips, and my scanner later showed the same code. What tests would you recommend next in order to isolate the problem? What is the likely culprit?
have the same problem?
