freeze frame for P0500

[fmugur]

I got the following:


I thought that it would be a speed sensor but it might not be. I have been reading other forums that they mention a camshaft sensor in fixing this problem.
This error first came out after cleaning the body throttle and I thought it was just a coincidence that the speed sensor fail in the same time and I replaced the rear left sensor which I found that it didn't have the same impedance as the others. Replacing the sensor didn't fix it. What does the freeze frame tell me?
Did I mess up something by cleaning the body throttle?

SES, DSC, Brake, ABS lights are also on.
