Coolant temp gauge

Ok so my issue is, my temp gauge is not working. Every other gauge on the panel works fine. Plugged in my meter and it’s not throwing any codes. Also, I replaced the coolant temp sensor. Any ideas?

 

What year/make vehicle are you working on in case you might need FSM schematics for troubleshooting purposes ?

 

It is a 2003 tundra v6 sr5

 

Adding that info to your profile can be a big help !

Attached are applicable pages from 2003 FSM showing checks one can make !

 

Thanks so much! This goes a little bit above my knowledge but I can dive into it if need be. With all of these possible issues in the pdf, do you think just replacing the instrument cluster would work? I can get a pretty cheap one from the junk yard near me. Thanks again

 

In all honesty, if those 3 checks are beyond your capability, replacing the instrument cluster would be a quick and dirty way, if it is indeed "cheap".

What happens if you tap the cluster in the area of the temp gauge, do you have needle movement ?
