ECT sensor help needed

[Harry_VW]

My cluster gauge is not currently working. I have been trying to figure out why but have not succeeded .

My plug and sensor have three prongs, can anyone confirm that two are for the ECU and one is for the cluster gauge?

So far:
grounded the cluster prong on the plug and the cluster gauge moves all the way round.
measured the voltage on the plug to see if it is getting power, it is.
Checked for continuity between the 2 ECU prongs, it beeps.

measured the resistance between the two ecu prongs on the sensor and turned the engine on, the resistance drops which is good?

So that means the plug and sensor are working independently but does not want to work when plugged in?

I'm so confused!

The reason that you are not getting any replies is that no one has the slightest idea what you are talking about.

Maybe a post on a forum specific for your bike (ideally with pics about what you’re referring to) would get you some answers?

As above, I’ve absolutely no idea what you’re talking about!

You're confused?

How do you think we feel?

What vehicle, what year, what are you talking about?

Apologies! Its an 05' Honda Hornet 600cc.

I tried the HH fb group but unfortunately they couldn't help

Engine Coolant Temp sensor?

Yes

Have you tried replacing the sensor?

Your cluster is working fine - just showing no engine temp?
