This is a serious issue and should be addressed immediately. Driving with low oil pressure can lead to catastrophic engine damage.
Possible causes include:
* Low oil level: Check your oil level using the dipstick. This is the most common and easiest to fix. Add oil if needed, but don't overfill.
* Oil pump failure: The oil pump may be failing to adequately circulate oil. This requires a more extensive repair.
* Blocked oil passages: Sludge, debris, or a clogged oil filter can restrict oil flow. Change the oil and filter, paying close attention to ensure no blockages.
* Worn bearings: Worn engine bearings can increase the clearance and lower oil pressure. This is a major engine repair.
* Faulty oil pressure sensor: The sensor itself might be faulty, giving a false low pressure reading. This is relatively inexpensive to replace but should be checked only *after* confirming adequate oil level and oil pressure with a mechanical gauge.
* Leaking oil: Check for any oil leaks around the engine.
Do not continue driving the vehicle with this code. Have it towed to a qualified mechanic for diagnosis and repair. Ignoring this warning can result in severe and expensive engine damage. A mechanical oil pressure gauge is strongly recommended to verify the reading of the sensor before replacing it.
