Sensor type on older 912 UL

912 sensors are physically the same as always ( see the relevant illustrated parts catalog IPC for details) . The most recent 'sensor change' is if you have updated to the "new-style" cylinder heads - in which case you need to reconfigure gauge settings of "Cylinder head temperature' to now measure "coolant temperature". See the video https://www.rotax-owner.com/videos-topmenu/rotax-minute/448-newcylheads 

Hi

Old model means that you are going to measure CHT and not water temp, unless you or some one else changed the cylinder heads to the new style, so when you start the configuration of the Engibox you must choose the option 912 CHT. Doing that the Engibox will be configured correctly.

The temperature sensors that came with the engine will work well but

From my  experience (I´ve one installed) for the oil pressure you should consider a Keller type sensor (most of the resistive VDO doesn´t work) and for the EGT sensors I suggest you to by from AVMAP, I´ve tried very expensive others and none worked.

Thank you both. Your answers were very helpful.

Dear Admin,

Since my last post I have put no small amount of time into this and the oil sensors are NOT the same.

The Oil Temperature Sensor that fits my 912UL has a much coarser thread than the one called out now. You can see the sensor that fits in my 912UL here:

If you go to the CPS website and look for the CURRENT 912UL Oil Temp sensor, you get this:

As you can see, they are different threads.

Overall, I think my problem is that the one that fits in my engine is a 400ºF sensor and the one AVMap EngiBOX assumes it is monitoring a 300ºF sensor.

My next challenge is to find a 300ºF sensor with the M10x1.5 thread pattern.

By the way. If you are troubleshooting low oil temperature, here is a great guide I found while researching the ThermoStasis Oil Thermostat that has been mentioned elsewhere on Rotax-Owner.

It is methodical and helped me finally resolve my issue.
