Hi I'm Peter your code P0720 Output Speed Sensor Circuit Malfunction This diagnostic trouble code (DTC) is a generic OBD-II powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may vary depending on the model.
On electronically controlled transmissions, the Output Shaft Speed Sensor (OSS) is located on the end of the transmission before the drive axles or driveshaft to read the speed of the output shaft which may be used to determine shift scheduling, torque converter engagement schedule and Electronic Pressure Control (EPC) inside the transmission. The Powertrain control module / Engine control module (PCM/ECM) has determined there is a malfunction with the OSS sensor. The PCM/ECM may substitute values based on other sensors to determine shift timing, torque converter operation and EPC pressure if the OSS sensor information is unavailable. The OSS sensor is also commonly used for the speedometer. Note: On some vehicles, the OSS sensor is inline with the Transmission Fluid Temperature (TFT) sensor, if there is a failure with the TFT sensor or associated wiring, the OSS sensor may malfunction as well. If there is another code associated with the TFT sensor as well as the OSS sensor, suspect a possible problem with either sensor, or the wiring in between

SOURCE: Where do I find speed sensors on a 2003 Nissan Murano?


P1574 is the ASCD Vehicle Speed Sensor so it would be relative to your speedo problem.

P0720 is the out put speed sensor, And the sensor is going to be towards the out put shaft to the axle. 
Good luck and hope this helps.

Where is the reset for 2007 nissan sentra fuel pump


How To How to Reset the Computer on a Nissan Sentra When the check engine light illuminates on the dash in a Nissan
Sentra, it is an indication that the computer has recognized a problem within its sphere of influence. Once the problem has been addressed and corrective action completed, the computer can be reset by erasing the existing codes.
jQuery('.intro .thumbnail').each(function(i,e){ jQuery(e).find('img').one('error',function(){ jQuery(e).remove(); }); }); Instructions Things You'll Need:
  • Code scanner
  1. Step 1 Insert the code scanner's connector into the OBD port located under the dash to the right of the steering column.
  2. Step 2 Turn the ignition key to the run position. Make sure the engine is off.
  3. Step 3 Press the button for "Read" on the code scanner. Within less than 1 minute, the scanner will display all failure codes that are stored in its memory.
  4. Step 4 Write down the failure codes displayed by the scanner. Cross-reference the codes with the code sheet that comes with the scanner. The codes are displayed with a letter followed by a four-digit number code. Deciphering these codes by cross-referencing them with the code sheet offers an explanation of the failure.
  5. Step 5 Turn the key off. Correct the failure so that the computer can be reset.
  6. Step 6 Turn the ignition key on, keeping the engine off. Press the "Erase" button on the scanner. Start the vehicle and allow it to run for 5 minutes. Watch for the check engine light to come back on. If it does, the problem has not been corrected. If it stays off, the problem has been successfully resolved.
