i have a 2000 450 es.oil temp light goes on even when cold.is this a known problem with the sender or is more likely the wiring to it?

how long were you driving when that light turned on? was the oil cooler pluged with snow? are you runnin Honda 10w40 oil or Syn.0w40?

Does it just turn on and off whenever with or without turning the fan on? The one in my 400 acted up and it was the control unite.

 

[fatsam]

it comes on when cold or anytime.runs cool.nothing obvious.

The cooling control unit & oil thermosensor would have to be tested ..
