Check engine light on, CC flashing, and Vehicle Dynamics Control off light on - Oh my!

Asked by Apr 06, 2017 at 09:48 AM about the 2009 Subaru Forester 2.5 X

Question type: Maintenance & Repair

So, my check engine light is on, cruise control is blinking, and vehicle
dynamics control off is lit up. I drove through a large puddle this morning -
totally caught off guard. Was in 4th gear when I went through it. The car
basically revved when I was in it, switched to first gear and drove through it.
No more than a foot deep. There was an unpleasant smell (like when you
peel out) even though I didn't hit the accelerator hard. Car sounds totally fine,
so I'm hoping the lights will turn off after it gets a chance to dry out...
Thoughts?

Probably the water. I would check the condition of the oil and trans fluid if the water was high enough to leak in. Scan for the codes to find out what is tripping the light.

Fluids look good. Code is P240, so I'm hoping a sensor got wet and it'll disappear in a couple days. Fingers crossed!

Try three restarts; if CEL still on then try an overnight battery disconnect; still on? Get a scanner to erase CEL and see if it recurs after two restarts. Google P240 if you feel like it. A foot of water shouldn't get into the motor nor trans, but if you haven't changed your ATF in a couple of years do it anyway.
