    p0500 code

    I just got a p0500 code. The check engine light is on, abs, and all those goodies.
    Now i believe this way be from rain/ water. It is pouring and i had to go through some water on the road. Not high water, just a good amount covering the road. Does this sound like its going to dry off and go away? I have read some stories about it on and the next day its fine. Someone also posted that it came on when they washed their car.

    Why don't you try resetting the ECU. Who knows if it will go away. Could be because of the water or could be cause of an actual problem with the speed sensor.

    I did with my ap and it just stays there. Another thing I remembered was I did loose traction for a sec due to the water. If someone knows where this sensor is located I will try cleaning it. 08 wrx

    It's also in limp mode I believe. And the idle is low/ rough

    Anyone?? Could a wheel bearing cause this to throw a code?

    The speed sensor is in the transmission.

    No... Well there may be one there also but there is one on the front wheels as well. It's on the opposite side of the caliper. And it goes inside the wheel bearing. I believe it may be the wheel bearing because I fixed a axle seal and had the axle out. Maybe it got dirt inside the bearing or something.

    Are you talking about the ABS wheel sensor? Clean it and see.

    I did clean it. Nothing has changed. I also started to hear a weird noise. It's hard to describe but sounds like something is rubbing or a slight grind
