What is the purpose of the EVAP purge system?
The canister purge valve is a vital part of the Evaporative Emission Control System (EVAP). The EVAP system seals the fuel system of your vehicle to prevent harmful fuel vapors from entering the environment.
How does the EVAP system work on a Hyundai Santa Fe?
The EVAP system captures all fuel vapor from the fuel tank and sends them to the engines intake in order to be ignited in the normal combustion process. When there is a small leak in the Hyundai Santa Fe’s EVAP system, it will throw the P0456 OBDII Code.
What happens when a Hyundai Santa Fe has a leak?
The EVAP system captures all fuel vapor from the fuel tank and sends them to the engines intake in order to be ignited in the normal combustion process. When there is a small leak in the Hyundai Santa Fe’s EVAP system, it will throw the P0456 OBDII Code. If there is a large leak, it’ll throw P0455.
How does the Hyundai Santa Fe OBD-II system work?
At first, the OBD-II system checks if vapor generation due to fuel temperature is small enough to start monitoring. Then it evacuates the evaporative system by means of PCSV with ramp in order to maintain a certain vacuum level. The final step is to check if there is vacuum loss by any leakage of the system.
What is the trouble code on a Hyundai Santa Fe?
This trouble code references a number that is given to you when you plug your Santa Fe into a OBDII scanner. P0456 Indicates that there is a small leak in the evaporative emission control system.
