What does the p2401 code on a Toyota mean?

P2401 TOYOTA Meaning 5 hours after the ignition switch is turned OFF, the electric vacuum pump creates negative pressure (vacuum) in the EVAP (Evaporative Emission) system. The Engine Control Module (ECM) monitors for leaks and actuator malfunctions based on the EVAP pressure.

What does the trouble code p2401 mean on EVAP?

The P2401 trouble code is telling us the EVAP control circuit has had a fault with the leak detection pump. The leak detection pump is used by the ECM to pressurize the EVAP system to check for leaks that are present. When the ECM has detected the the circuit has low voltage it will trigger a P2401 code.
