It indicates that there is an issue with the Evaporative Emissions System. It'll often appear with
P144C - Evaporative Emission System Purge Check Valve Performance Description: The EVAP check valve test is performed during minimal boost conditions, once per drive cycle, when entry conditions are met. This DTC sets when the fuel tank pressure exceeds a calibrated amount within a specified amount of time during the test. When using the Evaporative Emission Leak Detector With On Board Nitrogen Generator 218-522C or equivalent, the fuel level in the fuel tank must be less than 85% full. Normal Operation and Fault Conditions. For additional information on the EVAP system, refer to the Evaporative Emission (EVAP) Systems description. DTC Fault Trigger Conditions Diagnosis and Testing. Lincoln Navigator 2018-2024 Workshop Manual / Engine / Evaporative Emissions - 3.5L EcoBoost (272kW/370PS) / Evaporative Emissions. Diagnosis and Testing. Diagnostic Trouble Code (DTC) Chart. Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Here are the steps you can take to repair the system: Check the gas cap: A loose or damaged gas cap can cause the P0441 code. Make sure the gas cap is tightened properly and in good condition. Inspect the EVAP system hoses: Inspect the hoses for any cracks, holes, or damage. Replace any damaged hoses.
An Evaporative Emission System (EVAP) leak is where fuel vapors that are contained in the EVAP system escape. When fuel vapor escapes, it can be harmful to the atmosphere. ...

Visually inspect and push and pull on each of the following EVAP connections to verify a proper connection: Vapor line connections to the vacuum port side and pressure port side of the ejector. Refer to Figure 1 for 3.5L and Figure 2 for 2.7L. Vapor line connection at the port on air intake system (AIS) duct at throttle body ...Summary. The evaporative emission control (EVAP) system traps fuel vapors in a vapor canister, preventing them from being released into the atmosphere. EVAP systems can leak after some time. Depending on the size of the leak, the powertrain control module (PCM) can store a few related diagnostic trouble codes (DTCs).
If the ECM attempts to activate the vent control solenoid but detects incorrect voltage feedback or incorrect vacuum or pressure feedback, it will lock out EVAP function, set a diagnostic trouble code (DTC), and illuminate the malfunction indicator lamp (MIL). DTC P0447 is defined as "Evaporative Emission (EVAP) Vent Control Open Circuit.".
The P0496 code indicates that there’s an incorrect amount of intake vacuum flow occurring in the car’s EVAP system. Any time this vacuum is higher than what the computer determines is appropriate, the codes will be set. While this code can occur with all brands, it appears to be most common with GM vehicles.
Whenever a device performs an EVAP system self-test, it closes off the system and opens the purge valve. To calculate the purge flow, the computer uses the gas tank pressure sensor to determine ...Description: The PCM monitors the complete evaporative emission (EVAP) control system for no purge flow, the presence of a large fuel vapor leak, or multiple small fuel vapor leaks.

The purge valve, also known as the canister purge solenoid, is an essential part of your Ford Fusion's evaporative emission control system. Its primary function is to regulate the flow of fuel vapors from the charcoal canister to the engine. By controlling the timing and amount of these vapors entering the combustion process, the purge valve ...Evaporative Emission System Incorrect Purge Flow Actuator Stuck On. Leak detection pump creates negative pressure (vacuum) in EVAP system and EVAP system pressure measured. Reference pressure is measured at start and at end of leak check. If stabilized pressure higher than [second reference pressure x 0.2], ECM determines that purge VSV stuck open.
One of the primary consequences of a stuck closed purge valve is the increase in pollutant emissions. The purge valve is responsible for controlling the flow of fuel vapor from the charcoal canister to the engine, where it is burned off. When the valve gets stuck closed, it restricts this flow, causing a buildup of fuel vapor in the canister.Video on diagnosing and repairing a P144C which is an Evaporative Emission System Purge Check Valve Performance on a 2015-2020 Ford Mustang.https://onlineaut...Code P0441 relates to the Evaporative (EVAP) emission control system.
