A fault code doesn’t yet mean the unit or sensor itself is faulty: often it’s the plug and connector leading to it.
Possible causes
- Low oil level
- Worn oil pump or bearings
- Clogged oil pickup
What you can do yourself
- Stop the engine and check the oil level with the dipstick.
- If there is enough oil but the oil pressure light is on — don’t drive, call a mechanic.
The explanation comes from the error code reference in the AvtoElektrik PRO app.
