      Hello I know I should post this somewhere else but not enough traffic on other threads...
      I'm a noob so any help is greatly appreciated.

      So my engine code is on and I got my car scanned. I got P0721 and p0720
      ever since this light turned on all the P, R, D, N, S are highlighted at the same time.

      Here is what it says

      P0721
      Definition: Output speed sensor circuit.
      Explanation: Open or short circuit condition.
      Probable cause: Poor electrical connection or failed output speed sensor.

      P0720
      Definition: Output speed sensor circuit range performance explanation.
      Explanation: Open or short circuit condition.
      Probable cause: Poor electrical connection or failed output speed sensor.

      I don't know if it is the speed sensors on the wheels or the "transmission" one?
