oil pressure sender replacement

[henriquerv7]

Hi Dynon,

Today i had prolems with my oil pressure sensor and need to replace them. I found locally a VDO pressure sender that is the same especification as the one came with my dynon kit. Can i use it instead of the kavlico?

The one that i have locally is the same as this : https://www.aircraftspruce.com/catalog/inpages/sender360-025.php?clickkey=13212

Sure can but be prepared to buy another one again later as they don't have a good record of reliability

That looks like it's probably the same one we sell, so it would likely work. But as Jake said, we moved away from the VDOs because they didn't hold up over time - many people found that them needing periodic replacement.

Dear Dynon,

Today i received the kavilco oil pressure sensor bought throught aicraft spruce. Removed the old one, and placed the new one, but no reading at all. Got the +5v from pin 18, the green wire to sensor input and grounded the sensor to the battery ground. changed the settings to sensor type 5 as installation request. Even with the engine off, i keep reading "---" blinking red on number and ems alarm "high oil pressure. What could be happening?

That should do it. What version of firmware are you running?

 

[skysailor]

Did you go into the setup menu and change the sender type to Kavlico?

upgraded to latest version today.

set up to type 5, as istallation instruction request, but also tried all other types from 1 to 4. All of them doesnt work. "---" blinking red and high oil pressure alarm  all time, including when engine is off

The only thing that i made is putting the ground wire directly into the negative of the battery (it was the near ground point of the sensor. should i put the ground in the ground pin of ems or this should not make diference?

That shouldn't make a difference if your grounds are all well-grounded together. But having that wire coming back to an EMS ground is ideal in this case. From your latest description, that's also what you'd see if the system simply wasn't seeing the sensor (ie, it's not really connected). If the sensor isn't actually getting the 5V from pin 18, you'd see this. Actually if ANY of the 3 wires weren't getting to the pin they should be getting to, you'd see this. So I'd double-check the wiring here.
