Default Speedo Issues

Preludes are not my thing here. So I will try to explain as good as possible.
1990 Prelude 2.05Si
B21 motor
5 speed
Front Steer only

Problem:
Speedo works when car is cold, warms up and absolutely quits and check engine light comes on. CEL must be off to smog car(thanks California)

This does not have a cable driven Speedo like honda shows by VIN

It appears to have a power steering speed sensor and then an electrical speedo take off on top of that.

Questions:
What can the problem be?
Can that P/S speed sensor be eleminated, and how?

You just need the speed sensor that sits on top. Unfortunately Honda doesn't appear to carry one and I can't seem to find an aftermarket one anywhere on the net. Your best bet would be to try to source one from the junkyard.
