What does code p0456 indicate?
Code P0456 indicates a small leak detected in the Evaporative Emissions (EVAP) system. The evaporative emissions (EVAP) system is designed to prevent fuel vapors from escaping into the atmosphere.
What does the code p0456 mean?
P0456: What does it mean? The Codes P0456 indicates that a very small leak is detected in the Evaporative Emission Control System (EVAP). The EVAP is a system designed to keep gasoline vapor from leaking. It’s part of the Powertrain Control Module (PCM) and may notify a Code P0456 when a very small leak was detected.
What does a DTC pending code of p0455 mean?

P0440 is the general code for a problem with the Fuel Evaporative Emission System. The P0455 code specifically indicates a large leak in the system, not a fuel leak, but one in the vapor recovery system.
Where is charcoal canister located in OBD-2?
The system allows for fuel vapors from the gas tank to be absorbed by charcoal pellets located in the charcoal canister (also known as EVAP Canister), and to be released to the engine air intake manifold at a later time. The system is controlled by the engine control module (ECM) via a vent control and purge control valve.
