How Does the EVAP System Work, and How to Replace Canister Purge Valve,Vapor Canister and Vapor Pressure Sensor on Hyundai Santa Fe?

The Evaporative Emissions Control (EVAP) system is intended to capture fuel vapors and return them to the engine, to be burned in the the intake with the incoming air/fuel mixture. They consist of the FTFNC, EVAP, VPS, CCV, 2WV, and PV out of which all but the PV are found under the car. If temperature of gasoline in the fuel tank increases, this creates vapor that increases the pressure within the close container known as the vapor pressure sensor that feeds back to the PCM. The vapors pass through a two way valve and are then accumulated in the canister until the PCM triggers the purge control solenoid valve hence intake manifold vacuum will pull the vapors into the intake manifold. This system goes in a closed loop once the coolant temperature of the engine is high, thus, the PCM controls the vaporization to prevent a rich air-to-fuel in the mixture. In the process of purging, fresh air from the atmosphere is required for pressure equilibrium and the valve of the canister is opened and closed by referring to PCM. Thus, the diagnostic monitor of the EVAP system compares pressure to detect a leakage, and in case of leakage, the MIL turns on. The PCM also supervises the canister closed valve and pressure switching valve in order to perform effective check up, and the sequence is to be continued, while the engine is in closed loop. When it came to objectives such as the purge control solenoid valve, the procedure was removal of the battery and the engine cover, disconnecting of connectors and hoses among others, with installation being the reverse of the process of removal. The similar procedures of disconnecting and reinstalling apply on other components namely the two-way valve, EVAP canister, vapor pressure sensor, and canister closed valve.

Hyundai Santa Fe Vapor Canister

The Hyundai Santa Fe Vapor Canister traps fuel vapors so that they never escape into the air to harm passengers and the planet. The Hyundai device is either located near the tank or in the engine bay and utilizes activated charcoal with countless tiny pores to suck up the volatile hydrocarbons that naturally build pressure in the fuel system. When engine vacuum opens up the purge valve, fresh air passes through the Vapor Canister and draws the stored fumes into the intake where they burn like ordinary gasoline. Early Santa Fe editions featured a simple Vapor Canister with a basic purge line, while later Santa Fe models included a replaceable filter, a canister vent solenoid and a fuel-tank pressure sensor to allow the engine control module to test the sealed system for leaks and activate a warning light if pressure fails to drop. Despite these refinements, the fundamental job of the Vapor Canister never alters, that of capturing vapor during parking and only releasing it when the motor can use it, which likewise improves mileage. Owners of any Hyundai manufactured under OBD-II regulations have the advantage of this smarter Vapor Canister, and every Hyundai Santa Fe on the road is powered by the same charcoal-based chemistry to keep emissions low.

If you are looking for affordable high-quality OEM Hyundai Santa Fe Vapor Canister, then you have come to the prime place. Our website provides a large amount of genuine Hyundai Santa Fe Vapor Canister at unbeatable prices. All our parts come backed with the manufacturer's warranty.
