Land Rover LR2 check engine light with code P2402 for evaporative emission system leak detection pump control circuit high on Land Rover LR2

Some Land Rover LR2 owners report experiencing issues related to the check engine light activating with the diagnostic trouble code (DTC) P2402, indicating a problem with the evaporative emission system. This code suggests that the evaporative pump may be shorted internally, triggering the light without causing significant drivability issues. Owners are advised to check the EVAP system for leaks and replace any faulty components to address the P2402 code. Additionally, inspecting the Evaporative Emission Leak Detection Pump and its components for visible damage, as well as testing wiring and connections, are crucial steps for resolution. Some owners find that performing routine Evaporative System Diagnostic Checks and re-reading DTCs can help identify further issues, such as those related to the purge valve. In cases of small evap leaks, further diagnostics may be required to determine the exact cause. Properly diagnosing and resolving these issues is essential for ensuring the functionality and emissions compliance of the evaporative emission system.
