Faulty Oil Sensor?

[Jonny7]

My 'Check oil' warning light came on the other day on start up, so I did what it said on the dash, but both pressure and level were fine. The next day the warning light disappeared, but this did not last long. The next day after visiting the petrol station, on it cam again at start up, and has been on ever since.
Has anyone else had this problem, or can suggest the likely cause.
Thanks
Jonny.

Blocked or duff oil pressure sender or wireing?

Checked to see if the wiring plug had come adrift and it was fine. The oil pressure is normal too. Do these have a float in the sump for oil level?

Must just be the sensor. I will get a new one, thanks.
