Temp Needle Guage Stuck

Yesterday I was during routine tune up, plugs and wires on my 95 Tsp 3.1L. The needle on temp guage always worked before and now it won't registered anything eventhough I know motor is normal temp range. Is it possible I jiggled loose a wire trying to reach behind engine to remove plugs? Where should I start?

Most probable. THe temp needle sensor is behind engine . It is separate form the computer temp sensor..so engine performance is not a problem.

Thanks LMP. I will locate it. This is such a good forum. I have 4 Transports, and one I use for parts.

Just had to push connector back together it works now. thanks...
