Code P1461 2016 Honda CR-V Description

The P1461 code indicates a malfunction in the Evaporative Emission (EVAP) system, specifically related to the Leak Check Module Pressure Sensor. This system is crucial for controlling fuel vapor emissions from the fuel tank and associated components, helping to reduce environmental pollution and improve fuel efficiency. The Powertrain Control Module (PCM) initiates a diagnostic test of the EVAP system after the vehicle has been turned off for a minimum of five hours and meets certain conditions, such as the engine coolant temperature being within a specific range. During this diagnostic process, the PCM manipulates the pressure in the EVAP system by opening or closing the fuel vapor containment valve. If the pressure readings do not fall within the expected parameters during this test, the PCM will store the P1461 code.
