Connection Between Driving In Heavy Rain

[24valve]

It seems that every time I drive for a period of time in very hard rain in which I hit puddles that splash my undercarriage, my check engine light goes on. This has happened two or three times so far, and each time it goes out after the rainy conditions are over. It just turned on again, in heavy rain, and it's still on, but I think it'll go out like it has before.

Is this pure coincidence or could there really be a connection between the water and the check engine light? Just wondering, I don't want to have to spend $50 to get the codes read for a false alarm.

Thanks in advance!

Water may be getting in your DME area behind your glovebox...access it from under the hood behind the positive terminal on the passenger side...you'll see a foam pad riveted with plastic pop-ins to the back of the bay under the windshiled cowl trim...pop it open and check the seals for holes and see if water runs outs...water tends to stay in there so it'll run or trickle out as you open it.

Also your "splash guard" for you engine bay...all the way at the bottom front under the radiator (looks like a big square plastic pan with an X pattern in it) may have fallen off completely...and you won't even know it unless you look for it and see that it is not there. This keeps water out of your engine areas.

This may be it, thanks a lot, I'll definitely check for that. The rain has stopped and the check engine light has gone out again as before, heh.
