a new problem for everyone

It's been a wet day here. Drove to work in heavy rain, idled through some 3 or 4 inch water running across the road a couple of times. Going through the I-10 tunnel in heavy traffic at 10mph and ding ding ding. The DIC says Engine Power Reduced with a big ! The engine light and the stabilitrac light come on and the car is clearly running on 4 or 6 cylinders. Luckily don't get stuck in the tunnel and limp the last 3 or 4 miles to work. After an hour of sitting in the parking lot the stabilitrac light goes off but engine light still comes on and car running on reduced power. Another couple hours later lights are off and car runs fine. Go to dinner after work rain has let up, no probs. After dinner driving home with lite showers on highway no ding ding ding but same situation, reduced engine power! on dic, engine and stabilitrac lights on, car running at 1/2 power. An added footnote. when slowing to stop you can feel a jerk on every downshift with the shift to first the most noticeable. Tranny seems to be performing properly. (Automatic by the way)

Luckily the dealer is a friend/customer of ours and we had dinner with him tonight and he's sending a hauler and loaner in the morning. We assumed a wet sensor might be tricking the car into dropping engine power thinking that the stabilitrac isn't functioning properly. Any experience or ideas appreciated.

Its in limp mode for some reason. If it's under warranty let the dealer figure it out.

If not under warranty, disconnect battery or pull ECM fuse for 10 minutes, reconnect and see if fixed.. I had a Harley go into limp mode for no reason today, then it went away. I'm still watching it though.

Definitely follow up on what they find, OP. I had to drive 20 miles through semi-flooded streets highway the other day. No issues, but if water caused yours, it would be good to know.

Interesting. They just came and loaded her. After sitting overnight in the carport where she still gets wet but not poured on (it's still raining non stop here) the engine light was still on at startup but not the stabilitrac. Last night I cranked her four or five times before the engine light went off and power returned to normal. So I'm hoping the lights still on at the dealer. Power seemed restored when we loaded her even though engine light was still on as I said, so I'm perplexed. Maybe the start up mode (choke) caused it to seem normal, it's hard to tell just pulling her down the driveway and onto the hauler. I'll update whatever I learn.

I think you're on the right track with the wet sensor idea... its happened to be in the past. Probably not a wheel sensor though, because while it will cause ABS/Stabilitrac type issues, it probably won't cause the reduced power mode. My guess would be water in one of the front O2 sensor connectors, causing bad readings and forcing the car into open loop operation. The power would also be reduced if the throttle position circuit is bad, but not as likely that water would get into that.

Thanks again, I'm taking notes of everyones input in case the dealer can't solve the issue. This site has been beneficial and fun since day one for me. I'm all ears (or should I say eyes) friends.

I apologize for the frustrations you are experiencing from this issue. That is great that your dealership is taking care of the situation for you. Please let us know how service goes and if everything was addressed.

Please post up whatever you find! I didn't have this problem this weekend, but I can see where it could happen. I drove through downpours all the way from New Orleans to Atlanta on Sunday coming back from the Hot Rod Power Tour. I've learned with experience to try to avoid large puddles of water, but you can't always do that on the interstate at higher speeds or with traffic. Good luck!

It should have recorded a trouble code in the computer, even if the lights go back to normal and it starts running right the computer holds that information for at least 50 restarts. So they can tell that the trouble is real and not imaginary.

Oh crap, Mike! Hope they can figure out what's up with that. I agree it probably fried something with all that deep water. Meybe someone didn't use enough seal-grease on a fitting somewhere.
My Mazda b2600i will choke when it snows a certain kind of snow. Sounds weird, but a heavy wet snow will have the engine sputtering and spitting. No one's been able to give me a good explanation except possibly it's to do with the humidity and air pressure. Real cold dry snow, no problem. Heavy rain is not an issue at all, deep water doesn't slow it down. Wet snow chokes it out every time.

from my understanding AND EXPERIENCE..

if you have an engine misfire.. all those symptoms will happen.

I had a plug wire with a hole in it arcing.. dry as can be and those were the symptoms.


check your wires from the coils to the plugs.. push to make sure they're clicked.. you should be good from here. my guess is the water may have splashed up to the wires and caused a miss do to a not properly seated wire.

They called yesterday and told me it was a sensor that sits low on the drivetrain. When they pulled it water poured out. Sorry for not remembering which sensor at the moment but when I get 'er back tomorrow I'll give a full report. I asked if there was a way we could shore this up so that it doesn't happen in the future and "we're on it".

Knock sensor? Steering wheel position sensor?
