Severity of P025A OBD II Trouble Code

I would say the severity of this code would be determined by your symptoms. If your car does not start, this would be severe. On the other hand, if your vehicle is operating normally and fuel mileage isn't being affected and this code is active, this isn't a very severe situation. That being said, neglecting any fault may result in further time and costs.
