The bars on my dash that show engine temp are always in the same position.
The moment the engine cranks over it shows 4.5 bars. Stays the same if I ride it all day.
Any ideas ?
 
I see that no one is answering up
All of my knowledge is on the early ones
But going to guess at how it works.
I think that the ecu is feeding 5 volts to the temperature sending unit (because it is also feeding other units is why it is dropping the volts to 4.5) so i am thinking that the unit is either has a broken resistor or a bad ground wire going back to the ecu or maybe the connector is not on tight.
To sum this up ecu is monitoring the voltage and is not seeing a drop.

Thank you for the input . Always held 5 bars , added a couple ounces of “water wetter “ and it dropped to 4.5 but stuck there shortly there after . I don’t think it’s related but bears mentioning .
Loose connection or bad relay sounds like a good place to start.
 
Yeah, that’s not right. I’ll check mine tomorrow but it starts up low, 0 or 1.
