Code result
P055F
Engine Oil Pressure Out of Range
Moderate severity
What it means
The measured oil pressure is far outside the expected range for current engine speed and oil temperature - either too low (oil pump weak, oil level low, bearing wear) or anomalously high (relief valve stuck closed, blocked oil cooler).
Is it safe to drive?

The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
