Oil pressure switch or oil level sensor?

[Maserlove]

Hello,

I have an issue with the oil lamp, its flashing.

The instrument cluster is saying "check oil level".

Oil level is of course fine. Just to be sure I read the trouble codes from the ME9 with a Launch X431.

And it´s saying Engine Oil Pressure Sensor (plausibility) and Fault code is P0521.

So which of them both I need to replace?

I’m going to go with the pressure sender.

If you go into live data on the launch you can see what the sender is reading.

I checked the live data but couldn´t find the reading.

Maybe I have to check again tomorrow.
