I have owned my 92 Civic lx for 4 years and ever since I had it the temp gauge has never worked. Every single needle and light works except the Temp.

I had overheating issues due to a stuck thermostat (reservoir filled and overflowed when engine was hot). I jumped the temp sensor to no avail. I don't think it's a fuse problem but I will check them.

What are my options? Can I find a used cluster and replace the temp gauge that way?

Any help is appreciated

 

Have you bled the cooling system?

The 1-wire sending unit is located below the distributor:

 

Thanks for the reply.
I have done the gauge test and it did not move.
The fan works, thermostat works, coolant is bled.
Any other ideas?

 

If the Yel/Grn wire has continuity between the sending unit and cluster, then replace the cluster.

 

Thanks will check as soon as the heat goes down.

Care to share from what book these schematics come from?

 

A search should lead you to the discovery of a downloadable 92-95 Civic service manual. (HT members are not allowed to post such links)
