This is my first post and im already posting for help. im new here and to the honda world and hopefully someone with a little insight can help me. I recently bought a 1998 Honda Accord Lx with the v6. When i test drove it it ran beautifully. Drove it for about 3 days and then the cel light came on. I took it to advanced auto and had them run the scan and found it to be the gas cap. I changed the gas cap and it was fine for about 4 days. The other night i started it up and it was running for about 5 minutes and the cel light came on again. It didnt change how it ran or drove it was just on. I disconnected the battery and cleared the codes and it hasnt came on since, but i was just wondering what it could be? Im thinking it might be the o2 sensors but i would like a little insight on what else it could be.

 

What code specifically are you getting?
The issue with the gas cap has to do with EVAP relates emissions components which are unrelated to the O2 sensors.

 

I dont know. The guy that ran the codes sai it was the gas cap. Next time it pops up ill take it back and have them run it.

 

When they run the CEL light, ask for the printout. It should list the code & a few probable causes as to why that particular code came up

 

It came on again and it came up code p1456 which is evap systim control leak. How do i fix this and if i cant what would be the average price the dealer would charge

 

Code 1456 is an EVAP fuel tank emissions leak detected.
Right off the bat I would think gas cap, but you said you already replaced that.
Did you replace it with an OEM cap or something cheap from advanced auto?

I can only speak so intelligently regarding your year Accord because I don't own one and can only offer suggestions based on what I know about my 96.

With that said, my EVAP system has a valve at the top of the tank to bleed off excess fuel vapor trapped inside the gas tank.
A leak in this valve, gas tank, or any part of the vapor line running to the charcoal canister, would cause this code.

Your EVAP system is likely to be similar, I just don't know for sure though.

Assuming the gas cap is not the issue, troubleshooting this issue could be difficult to impossible for you depending on your level of proficiency working on cars.

Additionally I have no idea what a dealer might charge for a repair because the problem isn't even clear at this point.
Good luck.

 

Thanks for your input, i appreciate it. As for gas cap, i replaced with a cheap one from advanced, could the oem one fix it? I guess i have to call honda, im proficient working on cars but dealing with fuel system ill let a professional deal with it. Could driving with this cause further problems
