This is the range for the most common fix, diagnostic scan (check engine light). Which repair your car needs depends on a proper diagnosis.
The oil pressure sensor is reporting low oil pressure. That may be real, from low oil, a worn pump or worn bearings, or it may be a failed sensor. The dash light looks the same either way, so the oil level should be checked right away before driving any further.
- Safe to drive?
- No, get it looked at first
- Most common cause
- Low oil level
Check the oil level now. If the level is low or the oil light is on, do not drive. Low oil pressure can destroy an engine in minutes.

- Ask for a written OK before any extra work. Many states require written authorization before repairs.

P0522 questions
Can it be just a sensor?
Yes, and a mechanical gauge test shows whether it is. The shop screws a gauge in where the sensor goes and reads the actual pressure, which tells them whether the engine is healthy.
Should I add oil?
If the dipstick shows low, add the right grade and have the leak found, since low oil is the simplest cause. Keep an eye on the level over the next days to see whether it drops.
Is a tow wise?
If the oil light is on and the level is fine, yes. Driving with real low pressure can destroy the engine in minutes, so towing is far cheaper than risking the repair bill.
