it wont damage the engine itself but if a code was thrown check it at a local autozone for free to see what triggered the cel. the only thing i can prob think of by running into a puddle is maybe the impact of the water hit a wire? sensor? shorted something electrical that was exposed? could be alot of stuff till you get that cel checked.

did you happen to speed through the puddle? how deep with the puddle? if you did happen to speed through it , lucky you didn't hydroplaned and only the cluster threw off a light. And i agree about a wire sensor acting up because it got soaked/etc. An undercarriage cover would be very helpful if yours came off already.

There's no such thing as "hydroblow". Hydro-locking your engine is possibly if your intake was submerged under water or somehow water was sucked up into the intake tract. OP, what I would do in your case is to look at the ABS sensor wire and the vehicle speed sensor for any cracks or damage. It looks like the moisture threw the engine code but once the water evaporate and the sensors dry off, the problem goes away.

The simple answer is yes, it can. The chances of it happening are pretty small unless your an incompetent driver. Typically if you go in a large enough puddle to do damage to your engine, usually you also ruin other things as well. The ways you can damage an engine are to either submerge the engine in water to allow any exposed leaks or cracks to take on water. If water gets into the engine, you can do the about, which is known as hydro-locking a motor, usually resulting in bent or broken something. The way would be to dilute the oil to thin that it doesn't have the protective properties which allows for some metal to metal contact. The answer is yes, but I doubt you did anything serious, but word to the wise, avoid large puddles. CEL is a good sign, a damaged engine wouldn't likely run long enough to get a CEL.

Of course that can happen only if the engine or intake is SUBMERGED. running even over about a foot of rain puddle would not hydrolock an engine/damage it internally like you claim (broken rod,piston,valve,headgasket), unless the op has a CAI hanging down towards the floor. or if that puddle reached anywhere near his front bumper. if thats the care then like the above poster said, he is an incompetent driver.
great advice. pause. NOT.
Water can get in your engine through puddles. And if enough gets in, it can damage it in the exact ways I mentioned. Your car does not need to be submerged to have it hydrolock. IF you're going fast enough, hit a large/deep enough puddle, your air cleaner can suck water into the intake manifold and damage your engine.

I drove through a big *** puddle today... Put a kid in there and he could have gone swimming in it. I couldn't stop in time. It was too late when I finally realized it was a huge puddle that was about a foot and a half deep. I made it through without any problems and I was doing a good 35 mph. It felt like hitting a wall.
