848 Oil Pressure Sensors

Hi all,

I had the oil light come on with my 09 848 and it goes out when revved, all levels fine and no noises.

Tried doing a search on here for the part number and came across this alternative but was in a 999 post

Does anyone know if this is a safe and suitable replacement for the 848 or is it a call to the dealer?

Any thoughts/advice appreciated

 

Thanks for confirming, I will get one tomorrow

 

Hi all,

Bringing this thread back up as my oil pressure sensor has failed again, from what I have read in various places it can be common on the 848/1098, has anyone had the same issues?

I carried out an oil pressure test today before fitting the new sensor and got the following readings
1400 RPM - 50psi @ 82deg C
3600 RPM - 85psi @ 102deg C

The manual stated greater than 0.8 bar at 1100-1300 rpm and it should be greater than 4 bar at 3500-4000 RPM with minimum oil temp of 80 deg C

It also states max oil pressure should never exceed 6 bar

When I carried out the test it was quite difficult to keep a constant rpm while checking the gauge but when up at 4K and above RPM I noticed the oil pressure was more than 6 bar and I'm now wondering if this is the reason my switch is failing and obviously the cause of the high oil pressure.

Does anyone have any experience of this issue or know what the relief valve is set at. Or possibly a schematic of the oil system.

Any help or advice appreciated

 

It only really gives me the info I stated above regarding what it should be I.e above 4 bar but never exceeding 6 bar

 

Forgot to say, when I said it has failed I mean, on both occasions the light came on then oil started passing through the sensor from mechanical part into the electrical side causing it to leak at the wire connector.

This is the reason I'm wondering if high oil pressure is causing the sensor (possibly weakest link ) to fail

 

Yes, that was all ok, I
have also increased RPM to see if the relief valve is operational, I would say that is set a 6.5 bar but never found anything referring to setting in the manual or online.

 

Yes, Breather was ok,

This might explain things then, I did read on a few other forums they were notorious for failing and people just completely remove them and plug the hole.

That's not something I want to do and would prefer to find alternative solutions, I will have a look into moving the sensor to the same as an evo set up and what's required.

Thanks for the help
