P053A OBD-II: Positive Crankcase Ventilation Heater Control Circuit /Open
P053A Severity
Will P053A 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 P053A?
The Positive Crankcase Ventilation (PCV) Valve contains a heating element to assist the PCV valve in reaching operating temperature faster. If the engine control module (PCM) detects an incorrect signal from the PCV valve, the PCM will set code P053A.
