Severity of P2214 OBD II Trouble Code
Most times, I would say, emission related codes will be fairly low on the severity scale. Especially comparing to some possible hazards in other systems on the vehicle like steering, suspension, brakes, etc. Point being here is that if you have bigger fish to fry, so to say, you can put this on the back burner for now. That said, any electrical fault should be attended to with a certain sense of urgency.
