If you are experiencing a P0500 CEL, then it has to do something with your vehicle speed sensor. If you had recently messed with your suspension in any way, that may be the cause of your problem. In my case, it was because I was playing around with tire sizes in the rear and was running a sidewall that was too thick, causing it to rub against the rear bumper's plastic liner.
I was able to diagnosis my problem since clearing the code would allow me roughly ~20 minutes of normal driving (no limp mode/speedometer works) before the CEL would pop up again. So this meant that vehicle speed sensor was fine, but something else was causing the problem. After clearing the code, swapping my wheels out for another set, and going for a successful test drive, I was able to confirm that my wheels/tires were the cause.
Try clearing the code and see if it comes back on immediately (like within a few minutes of driving and your speedometer isn't working). If it comes on immediately, your speed sensor must have been damaged. If not immediate and your speedometer works up until your CEL pops up, consider all the suspension components that you may have messed with including wheels/tire.

-My car was recently in an accident and just got repaired.
Rear subframe,drivers side rear suspension and axle were all replaced (rear drivers side quarter panel too)
-My speedometer seems pretty accurate
-Every time I try to clear the code it come back on within 5 seconds.
-In terms of tires, it currently has regular primacy tires on the front and snow tires on the back (with stock rims all around)
