What does p0456 stand for in Nissan Altima?
The code technically stands for: System Small Leak– Evaporative Emission System 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 Nissan Altima’s EVAP system, it will throw the P0456 OBDII Code.
What does the error code p0456 mean?
First of all, this error code refers to the following: P0456 – Small Leak Detected in Evaporative Emissions System This means that the ECM (car’s on-board computer) has detected a vapor leak in the evaporation system. The leak is small, smaller than 0.020 inches, but it means that gas vapors are escaping.

When there is a small leak in the Nissan Altima’s EVAP system, it will throw the P0456 OBDII Code.
What does the Diagnostic Code p0456 mean?
The diagnostic trouble code P0456 code means that Evaporative (EVAP) Emission System SMALL Leak. Here you’ll learn everything you need to know about the P0456.
One of the most common trouble codes with the Nissan Altima is the P0456 code. This trouble code references a number that is given to you when you plug your Altima into a OBDII scanner. P0456 Indicates that there is a small leak in the evaporative emission control system.
What does leak test on Chrysler p0456 mean?
However, the ECM occasionally performs leak tests to ensure the evaporative emission control system is working properly. During the leak test, the ECM closes the vent control valve and purge valve to create a vacuum. If the EVAP system does not maintain the pressure, the ECM recognizes an evaporative emission control leak.
What is the EVAP code on a Nissan Altima?
