Did a search with limited results...

my '95 Civic Dx temp gauge does not work and the local parts houses cant tell me which sensor I may need to replace...

the water temp sensor or air temp?

any help would be much appreciated ~

TIA

Look on the cylinder head under the Distributor, you will see a sensor going into the head, its a 1-wire. This sensor gives feedback to the temp gauge on your gauge cluster. I have seen the connectors break off the sensor where it hooks on.

Thanks Matt, will look at that and see!

Matt93eg

No problem, hopefully its something simple like that. Also found this for you.

undrh2o

Thanks for the help! Especially the diagrams!!

I'm heading your way tomorrow to look at some wheels/tires, will be glad to buy you lunch for the help!!

Thanks again ~

Matt93eg

Nah you ain't gotta do that man, just glad I could help. Where you buying wheels/tires from?

undrh2o

Ad I found online for some Drag DR 23's, just says Concord...gonna get an address shortly and head that way in the morning.

Matt93eg

Sweet, good luck with your purchase, hope it works out.

If I end up buying I will post pics for everyones viewing pleasure...

in my experience that temp sender under the distro can become cooked and brittle from the motor heating up over time and break off quite easily.

already replaced the temp sending unit...did not fix problem

hows your heat? is it warm but not as warm as it should be? how cold is where you are?

im asking the condition of the t stat.

Also check the coolant level in both the radiator and reservoir.

undrh2o

Coolant level is good in both...looks like the gauge so I'm looking now for a new cluster, maybe one with tach.

thanks for the suggestions!

undrh2o

Ok...

replaced my cluster with another from an LX and still have the same "no temp gauge" issue...

I have checked the #15 - 10 amp fuse, replaced the sending unit and now the cluster with the same result...actually looks like the temp needle drops when the key is on.

any more ideas?

TIA

Did you ever do any of the tests in the posted diagram. Guessing solutions at random can get very expensive.

undrh2o

I did the testing, thats why I replaced the sending unit first...when that didn't work I replaced the cluster (wanted a tach anyway)

Former User

What was the result of the Sending Unit Test and Gauge Test prior to replacing either component versus now. I presume that your test results then and now do not fit with either being the problem. Instead, it sounds like a bad wire or connector between the sending unit and cluster.

undrh2o

grounding the sending unit wire resulted in no movement of the gauge when ignition switched on

impedence reading of unit itself was off a little but no it didn't indicate as being bad but I replaced it anyway...

I visually inspected the wire as far as possible without tearing into the harness and didn't see any break

I have the same problem with my temp gauge, cantseem to figure mine out either

Make new thread with more details.

Got it working, turned out to be a bad connector on the wire that plugs into the sensor
