| Subject: | Oil Pressure warning? |
Roger and others.
I have been flying this engine, 912ULS, 2000 model year about 1 year, 635 hours
total on the engine. One cold day this winter I started getting a high oil pressure
alarm intermittently? Oil temps running consistent 160 degrees, 60psi,
OAT in the 40's. Warm up is normal, fly for a little while and I will start
getting a high pressure warning on my GRT EIS. It will show low 90's for a few
seconds then bounce around between 60 and 90 occasionally going over 90 and
triggering the alarm. I can find no pattern? I changed the oil to a lighter
weight oil (not filter yet) as a test but no difference? What are the possibilities?
If it was going low I would be more concerned. It has happened each
of the past three flying weekends but only occasionally.
Thanks ahead of time.

Hi Dennis,
Four common items to look at here and none a big deal.
First the oil pressure wire may be loose on the sender so make sure it is tight.
The second item here that cause high pressure swings is a poor ground. This
is another very common problem. Check your grounds. The third item is the sender
itself is usually the culprit. Go to egauges.com and buy a new one for about
$30 if the wire wasn't loose. Third you have a 13 year old engine. You may want
to change the oil pressure regulator ball bearing, spring and plug screw to
the newer style regulator cone. It's about $80 and takes 5 minutes to change.
It will be one of these.

Dennis, I had the same thing in the middle of nowhere in
rural France and my Flydat was much aggravated! It turned
out that the wire to the sender was broken - the no signal
default reading being a high pressure, so odds on it being
a wiring defect.

Hello Roger.
What is the part number for the oil pressure sender for the Rotax 912 uls on the
egauges.com page?
Appreciate the help.

Had exactly the same symptoms, it was the sender. Roger has added extra things
to check for but if I was a betting man I would going for a faulty sender.
