What are the causes of the 322615 fault code?

It may be due to poor urea quality or poor fuel quality. Below is a related introduction to car maintenance: Introduction: Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Content: Modern car maintenance mainly includes the maintenance scope of the engine system (engine), transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. Purpose: The purpose of car maintenance is to keep the car clean, maintain normal technical conditions, eliminate hidden dangers, prevent faults, slow down the deterioration process, and extend the service life.
Last time my own car displayed the 322615 fault code, and I got a bit panicked. I quickly checked the information and found that it's mostly related to the engine control module, such as abnormal sensor signals or short circuits in the wiring. Specifically, if the oxygen sensor has excessive carbon buildup or loose connectors, it might falsely report a fault. Another common reason is a faulty fuel pressure regulator, which causes calculation errors in the system. Additionally, unstable battery voltage or corroded ground wires can also trigger it. That day, I tried clearing the code myself but it didn’t work. In the end, I drove to the shop for inspection. They plugged in the diagnostic computer and found it was an oxygen sensor issue—replacing it fixed the problem. Regular maintenance, like cleaning these parts, can help avoid such troubles, and the cost isn’t high.
