How does the evaporative emissions control system and Vapor Canister function and what are the symptoms of a fault in this system on Nissan Altima?

The evaporative emissions control works in in a way that it draws fuel vapors from the fuel tank and the fuel delivery system, stores it in a container with activated charcoal and then injects it into the engine where it is burnt. The sign that is most easily and frequently reported when it comes to a faulty system is the strong fuel smell in the engine compartment. If such an odor is found the charcoal canister is to be examined which is situated at the front side of the car's engine room and the canister with all the hoses has to be looked whether it has gotten damaged or whether it is wearing out.

What is the role of the Evaporative Emissions Control (EVAP) system and Vapor Canister and how to inspect and replace on Nissan Frontier?

When the engine runs, the Evaporative Emissions Control (EVAP) system collects fuel vapors, holds them in a canister filled with activated charcoal, and sends them through vacuum to the engine's intake system. When the engine is idle, the canister holds the vapors. The PCM makes the electronic purge control valve switch vapors into the engine while running. Diagnostics added to more recent models starting in 1997 help check the EVAP system's performance and find any leaks. The EVAP system may act up when the purge valve breaks down, the canister becomes damaged, or any of the connecting hoses wear out. Fuel smells and loss from leaks or worn hoses happen often. You need to check all parts carefully and fix anything that's broken. The canister must be replaced whenever it starts to crack or leak, but we can test the purge and vent valves using the same methods as we do for other solenoids. The EVAP system pressure sensor works like a MAP sensor, but it offers better accuracy as specific voltage levels tell us if all parts are working properly. Keep the system under 6.0 in-Hg pressure to maintain good health. To replace the canister on these vehicles, made after 1997, take out the canister from the left frame rail behind the fuel tank. On Frontier and Xterra models, find and remove the canister from behind the rear axle, on a crossmember. We must lift the vehicle, disconnect the vacuum wires, unscrew the holding screws, then do the opposite steps when putting the part back together.

How to inspect and check the vapor canister and associated hoses for damage or deterioration in the evaporative emissions control system on Nissan Pathfinder?

The function of the evaporative emissions control system is to draw fuel vapors from the gas tank and fuel system, store them in a charcoal canister and route them to the intake manifold during normal engine operation. The most common symptom of a fault in the evaporative emissions system is a strong fuel odor. If a fuel odor is detected, inspect the charcoal canister, located in the engine compartment on 1996 Pathfinders, or under the vehicle on all other vehicles. Check the charcoal canister for damage and the hose connections for cracks and deterioration. On 1997 and later Pathfinder models the charcoal canister is located behind the left rear wheel. On Frontier and Xterra models, remove the spare tire for access. Check the canister and all hoses for damage and deterioration. The evaporative emissions control system is explained in more detail later.
