Thank You More Power Again.

Everything I can find on your Sentra says that this is indeed a two wire VRS vehicle speed sensor. It'll produce an AC signal that you can measure with your DMM.

Are you posting from North America, or overseas? I ask because I've tried looking up info and diagrams for your Sentra, and none of them show the module that you posted pictures of. Here's the diagram I have:



This shows the VSS feeding into the speedometer (inside the cluster), which then sends a signal to the ECM. The VSS signal will be an AC sine wave, while the Speedo -> ECM signal is likely to be a square wave. Simplified, the signal goes VSS -> Speedo -> ECM.

If you have the ability to take DMM measurements on those pins with the front wheels spinning, then we might be able to figure out which pins do what.

Hello MOD, Thank you for you reply, my sentra is "carbureted" and its not ECM .
my speed sensor is located on the transmission
