My 98 Accord's engine check light has been on for a while. It used to come on once in a while and I would just open the gas cap and tighten it again and it would go off. But this time its been on for a while. Anybody knows whats going on?

 

EVAP system.... charcoal canister and vent shut valve.... that's wat i have..... been having it for abt 1 month now, but have no $$ to fix it.... $200 to fix it here at the dealership.....

 

Go to AutoZone & have them read the error code. Get the number, not just the guy's description, then come back. Even with the number, you still have to do some troubleshooting. For example I got P1457 EVAP canister system a while ago. There's a handful of solenoid valves, wiring, a 3-way valve, a pressure sensor, and a whole mess of vacuum tubing where it could POSSIBLY be leaking. You still have to find the leak.

Dark... If you REALLY know it's the valve, OK. That's what mine was, it was less than $50 & not too hard to replace. But still, you need to be sure it's actually the valve. It could just as easily be $1 worth of rubber hose that's torn, or a loose wire somewhere.
