2001 Nissan Sentra P0720: Location of Speed Sensor in Automatic Transmission
I own a 2001 Nissan Sentra with a 1.8L engine and am currently encountering error code P0720. Can someone confirm the exact location of the speed sensor in this model? The issue appears to be related to the transmission, specifically the input speed sensor (also known as the revolution sensor), which is critical for gear shift operation.
The correct component is the A/T Revolution Sensor — this is not related to the speedometer. It's located inside the transmission and plays a key role in monitoring gear position and vehicle speed for proper shifting. This sensor is common across several models in the same transmission series. For visual reference, check out this video: https://www.youtube.com/watch?v=SZuVCf6Z5Fg
