The P0720 code is activated when the PCM detects insufficient or erratic input from the output speed sensor (OSS). The code shows an "output speed sensor circuit malfunction." It points to a defective input/output speed sensor on the transmission. Click this link to see more details about this problem from our knowledge database. There is also a video tutorial (on the link, please watch it) on how to diagnose the issue. We do not have specific steps to guide you through how to use/test if you have a multimeter. It is best to refer to a friend or colleague for a real-time tutorial for such an activity. I hope this helps!
