Order of inspection
P2401 Evaporative Emission System Leak Detection Pump Control Circuit Low Low
The P2401 code means the computer sees low voltage in the control circuit of the EVAP leak detection pump, either a short to ground or a missing supply. The system cannot check for fuel vapor leaks and the EVAP monitor does not complete. It does not affect how the car drives, but it can keep you from passing an emissions inspection.
