P2407 error: Evaporative Emission System Leak Pump Sense Circuit Intermittent

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! P2407 is one of those “EVAP system is confused” codes—specifically, the leak detection pump sense circuit is acting up. It’s usually a wiring issue, a failing pump, or a bad sensor signal. The good news? You don’t need a wizard-level emissions tech, but you do want a shop with a solid scan tool and some EVAP system experience. A good general mechanic can handle this, especially if they’ve got experience with Mazdas or imports. Just make sure they can do smoke testing and know how to interpret EVAP-related data. Otherwise, you’ll be chasing your tail—and your check engine light. If you need any further advice or want help finding a trusted RepairPal shop in your area, please feel free to call us at 877-913-1554.
