I have a 1992 Camry LE 4cyl 2.2, the speedometer and tac stopped working it in. I replaced the two and that didn't fix it, then I replaced the speedometer instrument panel because I read that the clusters could be the problem, when I did that it fixed the tac but not the speedometer .. I am at a loss now, what am I missing? What else could cause this? any help is appreciated!

 

Make sure the Red/Blue wire to the speed sensor has 12V power.

And there is continuity between the ends of the speed sensor wires running between the sensor and panel. At panel and sensor ends the wires are Green/Black (panel) and Pink(sensor) and Green and Light Green.
