Smart P2403.40h -

A simple but common cause where a missing or poorly sealed cap prevents the system from maintaining pressure. YourMechanic Recommended Actions Inspect the Gas Cap:

: Generally indicates a circuit issue with the Evaporative Emission System (EVAP) leak detection pump sense circuit.

Smart cars are notoriously sensitive to moisture. The wiring harnesses routed underneath the vehicle to the clutch and gear shift actuators are highly susceptible to road salt, water ingress, and chafing. A corroded ground or a broken data wire can instantly break the connection between sensors and the TCM. 5. Weak Vehicle Battery or Voltage Drops
