Code P2402 2018 Toyota RAV4 Description
The P2402 diagnostic trouble code for a 2018 Toyota RAV4 indicates a problem with the Evaporative Emission Leak Detection Pump being stuck ON. The Evaporative Emission System (EVAP) is responsible for preventing fuel vapors from escaping into the atmosphere. The Leak Detection Pump is a component of the EVAP system that checks for leaks in the system by pressurizing it and monitoring for any drop in pressure. When the pump is stuck ON, it means that it is continuously running, which can lead to various issues.
