I checked connection from 2 oil sensors frone and read to ecu - OK
I checked ressistance 2 sensors 1 is normally open and second normally closed. 99% ok
Its possible voltage regulator rectifier cause this problem ?
I vw check faults by buds diagnostic - no faults even if I disconnect 2 plugs from sensors - it is ok ?

How old is the oil ? I had similar problem fixed by changing oil.

Change the sensors. They fail intermittently so they typically test fine.

 

[milkatrek]

I replaced 2 sensors front and rear. Front is normally closed - I think is ok.
Rear oil switch sensor should be normally open but mine is Shorted to gnd thats way I have error. If i disconnect plug then error P0520 dissapair but when engine go to 4000rpm then oil check ON.
Whats going on here ? Those 2 type oil sensor - normally open and close.

Seadoo changed from normally open to normally closed at some point. Are you sure you have the correct part number and sensor?

 

[milkatrek]

propably wrong. My oryg 256777 - I order 256886

 

[ski-d00]

Are you sure you have the front connector on the correct direction? It can be put on backwards.

 

[milkatrek]

everything is ok I think. Explain please

The wire clip should face the engine

The wire clip should face the engine

I found 2 type of housing oil separator. Sensor is in another place.
