P252A OBD-II: Engine Oil Quality Sensor Circuit
P252A Severity
Will P252A 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 P252A?
The Engine Oil Quality Sensor tells the engine computer the oil level, oil temperature, and quality of the oil in the engine. If this sensor fails, code P252A will be stored. The OIl Level and Oil Temperature display on the instrument cluster will not work.
