The primary function of the evaporative emissions system (EVAP system) is to regulate the engine and fuel tank vapors. It keeps the vapors from being released into the air by collecting them in an activated charcoal storage tank.
The evaporative emissions system pressure sensor switch is typically located on or near the fuel tank or within the evaporative emissions canister assembly. Its purpose is to monitor the pressure within the evaporative system to detect leaks and ensure proper functioning. In some vehicles, it may also be integrated into the fuel filler neck or connected to the purge valve. Always refer to the specific vehicle's service manual for the exact location, as it can vary by make and model.
There are multiple safety, environmental, and motor vehicle inspection problems which can result from neglecting a vehicle's evaporative system. These are the leaking of fuel and its vapor, and failing emissions inspections.
The emissions system used in cars is a system which is designed to restrict the amount of pollution cars produce. Newer cars have system which prevent both Evaporative Emissions and harmful Exhaust Emissions. The Evaporative Emissions (EVAP) system prevents the escape of unburnt fuel vapor form the fuel tank, the fuel lines, and the engine. The Exhaust system uses at least one Catalytic converter, which is used to burn off gasses produced by the engine. On newer cars, both the EVAP and Exhaust are monitored by the vehicle's computer, which can alter the way the engine runs and can warn the driver of EVAP leaks.

usually this means the gas cap is not on tight or is leaking
Evaporative emissions leak detection pump sense circuit range performance refers to the ability of the vehicle's evaporative emissions system to accurately detect and measure the performance of the leak detection pump. This circuit monitors the pump's operation within specific voltage or resistance ranges to ensure it is functioning properly. If the readings fall outside the expected range, it may indicate a malfunction or leak in the system, potentially leading to increased emissions. Proper performance is crucial for compliance with environmental regulations and maintaining vehicle efficiency.
