P051F OBD-II: Positive Crankcase Ventilation Filter Restriction
P051F Severity
Will P051F go away on its own?
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
What causes OBD-II fault code P051F?
The Crankcase Pressure Sensor tells the engine control module (PCM) how much pressure is building up inside the engine. If the pressure inside the engine gets too high, it can be an indication of the Positive Crankcase Ventilation (PCV) filter being clogged. If the PCM detects excessive pressure from the Crankcase Pressure Sensor, the PCM will set code P051F.
