MaximaNissan Factory Service Bulletin OBDII Code P0456 What does this mean? When is the code detected?Malfunction is detected when Evaporative Emission (EVAP) control system has a very small leak, EVAP control system does not operate properly. Possible symptoms- Engine Light ON (or Service Engine Soon Warning Light)- Possible a noticeable fuel odor caused by the release of fuel vapors P0456 Nissan Description This diagnosis detects leaks in the Evaporative Emission System (EVAP) purge line using engine intake manifold vacuum. If pressure does not increase, the Engine Control Module (ECM) will check for leaks in the line between the fuel tank and EVAP canister purge volume control solenoid valve under the following vacuum test condition.The vacuum cut valve bypass valve is opened to clear the line between the fuel tank and the EVAP canister purge volume control solenoid valve. The EVAP canister vent control valve will then be closed to shut the EVAP purge line off. The EVAP canister purge v
Emissions System - Small leak detected What does that mean? The Powertrain Control Module (PCM) at different times performs various tests on the EVAP system. OBD II Enhanced EVAP systems are in place to keep fuel tank vapors from venting into the atmosphere,

and instead purges them into the engine to be burned. Regular pressure tests are conducted p0456 nissan 370z by the PCM to monitor the sealed system for leaks. The PCM monitors the EVAP system pressure by watching the fuel tank p0455 nissan altima pressure (FTP) sensor. When the sensor indicates a small leak in the EVAP system, this code is set. Potential Symptoms There will likely be no noticeable symptoms other than the Malfunction Indicator Lamp (MIL). This is because the http://www.engine-codes.com/P0456_nissan.html EVAP system is a closed system and only controls fuel tank vapors, not engine management. Causes Usually this P0456 code is caused by an incorrect or faulty gas cap. Filling the fuel tank with the engine running could conceivable cause this code as well or if the cap wasn't properly tightened. Any of the following could also be the cause: A small leak in any of the EVAP hoses or fuel tank hoses A small https://www.obd-codes.com/p0456 leak in the purge valve or vent valve The EVAP Canister may be leaking Possible Solutions First, using a scan tool activate the vent solenoid, sealing the system. Then monitor the fuel tank pressure (FTP) sensor. If the system is sealing properly, the number will stay consistent. If is isn't, the pressure sensor will show that as well. If the system slowly leaks, use a smoke machine and watch for smoke exiting the system at any EVAP component. Any where there is smoke exiting the system, that is the faulty component. Do not pressurize the EVAP system with air pressure. Doing so can damage the purge and vent solenoids in the system.
