coolant sensor - poolredalligator - 04-30-2005 18:07
My coolant sensor may be acting up as the DDEC is returning a code of
low coolant. However, when I check the coolant level it is okay. The
only sensor I find is the one on the coolant reservoir. Is there
another one on the radiator in a PT40, 475 HP?? If so, where is it and
how do I get to it??

Gene:
Are you sure that is the only code you are receiving? I had that
problem last year. Nothing wrong with the coolant, but I had a leak
right above my oil pressure sending unit that had a hole in the
plastic cap from a loose compressor belt rubbing on it. I couldn't
see that code, but when we hooked up the code reader, there it was.
Take it by a dealer and check with the reader.

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.

Gene: No other ideas other than take it to a shop that has a reader
and have it checked. Simply clearing all the codes past and present
might just solve your problem.

Ron , is there a way to clear the codes myself. Stewart & Stevenson is the
only place I know of that has the means to read the original DDEC and they
charge
an arm and a leg here in Houston. Thanks,

coolant sensor - Bob & Carol Howald` - 05-02-2005 09:39
Gene: I had about the same problem a few years back on my 93pt. I
would get the low coolant flash code and also about the same time I
would get the check transmission light flashing when I would go from
bright to dim on the head lights. I bought tuner spray cleaner and
took
the cannon plugs lose and cleaned them well. I then went completely
over every ground strap on the coach. also added a extra one next to
the one on top of the transmission. After doing all that I have not
had
one problem with false code's or lights. It also corrected my
speedometer from running about 15mph standing still. Bob 93pt40

Hi Gene,
I am having the same problem with the low coolant code as yourself. I
have to overfill the tank to stop it from happening. I usually get the
check engine light flash when going up a long slope. I have not been
able to put my finger on the problem as of yet. If I find the cause I
will let you know. I do not think that clearing the code will solve
your problem. I have already tried that.

Bob, thanks for the input. I will try the same procedure. However, I would like
more information
as I have no experience with cannon plugs. Where are they located?? I have heard
that
you must have special pliers to remove some types of cannon plugs. How did you
remove yours? Also,
where did you purchase the tuner cleaner? Give me as much information
as you can as I have no idea where to begin. The ground straps are not a problem
as I previously installed
additional ones. Thanks for your help.

Thanks!!!!
