Fault code P1509, Lake temperature. Help
I have just rebuilt my engine after a valve drop. Now when putting the DESS on it shows SENSOR in the display and if i check the code it shows P1509 only.
Now the P1509 is "Lake temperature circuit out of range".
My lake temp and speedo shows correct and works fine
The engine starts and runs fine but i haven't tested in the water yet.
Any of you that knows why I get the P1509 code even when the Lake temp is showing correct?
Is this code indicating something else that can be wrong?
