Is the 95 or 98 200sx speed sensor compatible with the 97 200sx? And this is for the SR20DE btw. Thanks!

You can use the 95 but Im not sure about the 98 since they switched to a new style of ECU that year.

Thank you, turns out the trick to take the cluster gauge out and tightening the four screws that holds the circuit board on the speedo together got rid of the P0500 (Speed Sensor) CEL light and cruise control came back. Saved $50.

Now I have a CEL for EGR valve ($74)...one thing after the other...I had a O2 CEL too, but it went away somehow...I might take the EGR off and clean it before replacing it.
