see if you can find a mechanic with a smoke machine you hook it to one of the hoses and the smoke will come out the leak. lt could be loose hose clamp , broken plastic clamp, dry rotted hose ect , the gas gap is a item that can cause the light to come on always make sure the cap is on and tight. do the smoke see if it will find the leak most shops have one. it is what its for.

Could be your heater core leaking. Try some engine coolant "stop leak" in the radiator. Be sure to have the heat turned on when you do it, so the coolant and the rad stop will flow through the heater core for a while. I have the best luck with the stuff that is powdered aluminum . Pour it in your rad when it is low, and then fill to level. If that doesn't do it you may have to replace the heater core. Or, it could be just a hose leaking under the hood, and the fan is sucking it into the truck. Inspect all hoses and connections and gaskets closely .
It probably just drips until the coolant level get's low, and then steams forcing you to smell it.

Did you change the gas cap with a Honda gas cap? Tighten it at least three clicks?
Also, Honda recommends that you never top off the tank when getting gas (only go to the click-off of the pump; otherwise you can get back flow into the system that will cause the code).
Tightening or replacing the cap will not immediately cause the light to go off; it can take up to three days of driving for the light to reset.
To check if your readiness codes (emission system) are set, turn the ignition to ON (II), without starting the engine. The Malfunction Indicator Lamp will come on for 20 seconds. If it then goes off, the readiness codes are set. If it blinks 5 times, the readiness codes are not set.
You can, of course, try resetting your engine light to see if it will come back on (which it probably will). I believe the procedure is:
Turn off the engine.
Press and hold the Select/Reset knob (odometer) in the instrument panel, then turn the ignition switch to ON (II).
Hold the knob for approximately ten seconds until the indicator resets.
Hope this helps you.
