Speed Sensor necessary?

[torbsim]

Hello everyone,

when installing the instrument panel I noticed that the speed sensor was missing.

I am now unsure whether this was an extra that had to be purchased, or whether it was simply removed by the previous owner.

It would help me enormously if you could explain to me what the 73 speed sensor did, what functions it has taken over, and should I look for a new one before I put everything together?

Example:



Thanks Ben

That sensor was used by the emissions control system.

Here is the diagnostics for what the speed sensor is used for.

Thanks! Sounds to me like it's not necessary? I also have no EVAP installed in the current setup.
