coolant sensor

[vmarshall@...]

Ron, I am not receiving any other codes-always the 1-3 that reads lo-coolant
sensor. I
note that when I overfill the coolant reservoir the engine light does not come
on as often
but because the reservoir is so full, I lose the coolant and have to overfill it
again if I
want the keep the engine light from coming on so often. The oil pressure sending
unit
was replaced on June 7, 2004 so I don't think that it is the problem as
everything looks
fine there. Any other ideas you might have is certainly welcomed. Missed you at
the
Kerrville Rally.
