I reconnected the sensor to see if perhaps the connection would be better and did a short flight. Oil pressure fluctauted from start up ghrough taxi and run up all other indications were normal. Briefly the oil pressure returned to normal until take off roll and inflight. Fuel flow was normal.
I downloaded another diagnostic and sent it to Dynon Tech for evaluation.
My main question now is the oil pressure sensor in need of replacement or is there a short from the oil pressure sensor alone?
On a side note, my airplane is an SLSA RV-12 and I’ve seen that there is an option to install a remote oil pressure sensor? Is this an option for an SLSA having been approved by Vans or do I have to simply replace the oil pressure sensor in original location (if this turns out to be the reccomendation)?
The kit has not been evaluated by Vans for approval on SLSA Aircraft.
It is flying on a lot of ELSA rv-12 aircraft as well as a myriad of other Rotax installations.
In addition we have been able to adapt around the rotax service bulletin that has Rotax owners drill and re tap their engine for new metric style transfucers. If you would like to install the kit, I would recommend calling Vans and letting them know and see what they say.
The remote oil pressure relocation seems to greatly help with erratic indications that are introduced by vibration associated with direct mounting to the engine.
Here is a link to the page showing our remote install kit.
