Where is the "No. 1 vehicle speed sensor" on a 2001 Toyota 4runner?

Question

I can find diagrams for No. 2 vehicle speed sensor, but I need to look at my No. 1 VSS.

Looking in the field service manual, I can't see it either.

Where is my No. 1 VSS?

Answer 1

VSS 1 isn't really a sensor. On that car the VSC ECU takes input front the wheel speed sensors and sends a 4 pulse signal to the Instrument cluster. Which in turn sends a 5v square wave to the ECM.

This is explained with a circuit diagram and visual representation in the field service manual you linked in section DI-103.
