I will be going through that area Monday morning about 4:15 AM. That will be the test. I went through there traveling the opposite direction about 9:00 AM Saturday morning and the light did not come on. I do have a new Toyota OEM gas cap installed. I was planning on going through there Wednesday or Thursday morning but my job had a change of plans and I did not make it. I will post the results Monday morning.

Well, It came back on in the same spot this morning on the way to work. I have noticed they are doing some paving on the road about a mile before I get to this spot. They only work at night and shut down during the day. Do you think my car could be sniffing hot asphalt in that area and just takes that long to register it for sensors? I do know the smell is real strong when I come through their construction zone.

I am at a loss now. that is really odd. propane or natural gas lines around that area? this is really bizarre. the doesnt come on any other time?

That is the only place it comes on. It only comes on when I travel through there at 4:15 AM on Monday mornings. As I had said in an earlier post I went through there Saturday morning going the opposite way and it didn't come on. They have been working on the road about a mile before I get to that point. I do not know what exactly what they are doing but they could be dealing with a gas line. They have been working on it now for about three months. They only work on it at night from about 10PM to 6AM and then reopen all of the lanes for the morning rush. They tear up the asphalt at night and then lay it back down in the morning. When I go through there all I smell is asphalt. I have never seen a check engine light come on like this before.

I suggest you have your local Oreilly's read the fault code. This should help narrow down what exactly is throwing the check engine fault. It might also push you/us in the right direction for diagnosis.

The code is P0440 which is "Evaporative Emission Control System Malfunction". I have read the code six times now. It has all that it shows. The most probable causes for this code is faulty/loose gas cap, EVAP canister, leaking vacuum hoses and fuel tank leak. I have replaced the gas cap. The part I don't understand is why is does it where it does it and nowhere else? It happens on the way to work from my girlfriends house at the same location every time. I didn't realize it until about the third time. I have a code reader that will read live data from the OBD II. My next step will be to connect it to the OBD II port before I drive through there again.

I am still baffled by this. LOL! my cousin has a forester, he was getting the same code. but it was all the time. his evap canister had crack...... wasnt cheap to replace. but in your case it is weird that it is one spot that triggers this. keep us posted.

You need to brake (ort break) up with her - she might get to your boat next!

Is the route before that spot full of quick up & down hills? Big bumps? Or anything out of the ordinary that you don't encounter in your other travels?

Road construction. The way they have it set up it is like going through a slalom course. You go left and right and back left in quick succession to get through there. Maybe I have a vacuum line loose and when I go through there it leaks a little causing the light to come on? Could be. When I do read the code it is already classified as an inactive code. I have cleared the code within a mile of it coming on and it reads as an inactive code.
