today my engine and vsc lights on I don't know why or because its raining and drove in the flood and something got wet.

 

YOU WHAT how deep????

 

it happened to me , something it was rainy , i drove with water approx above tire , i got CEL , reset it ..
everything was fine .

 

How deep was this water you drove through? I would think if you got water in the engine it would shutdown on you immediately but you never know.

 

A CEL with VSC light on indicates the car has gone into limp mode. It could be a hiccup but pull the code and see what comes up. Limp mode or safe mode is usually triggered by events that the ecu deemed to be serious in nature to prevent catastrophic engine failure.

The flood water may have gotten into some connectors and caused a brief short. Things like a misfire, MAF sensor damage, etc will put the car in limp mode.

My suggestion...if the car operates fine. Pull the code, reset and let the car/ecu cycle through a few trips and see if the problem comes back up.

 

Pulling the code is the only way to truly understand what is happening and why. the secondary o2 sensors could have gotten wet and are failing, gas cap possibly not sealing, the possibilities are endless. Pull the code.

 

same thing just happened to me LOL. where's the OBD II port? i'll pull the code with my SCT tuner

 

under dash kick panel straight up from where your feet are.

I pulled code P0402. i'll research what it is. just pulled fuses and we'll report back once i ECU is reset

 

reset successful, but hope that code doesn't ever come back

 

the flood is only very low just on the tire. How do you reset the code/what kind of code. tnx all who replied

 

Just saw the link, tnx

 

sorry not really a flood, just water filing up on the streets maybe got wet under something in the engine. I just saw the link might do it tomorrowto pull the 2 fuses.
