These uncontrolled evaporative emissions account for as much as 20% of the pollution produced by a vehicle! When trouble code P0496 is set, it means that there is an issue with the purge flow in the EVAP system. Specifically, the Evaporative system is purging fuel vapors when it shouldn’t be. P0496 CausesP0455 - Evaporative Emission System Leak Detected (Gross Leak/No Flow) Description: The powertrain control module (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.Freightliner AC systems are much larger than most vehicle systems, and they use a larger condenser and an air compressor to cool the air. An evaporator is used on freightliner truc...Turn the smoke machine on and watch the flow meter check ball (photo 3). If there are no restrictions in the evap system, the check ball should be close to the top. If you want to be more precise, connect an inches of water gauge, as shown in photo 2. If the gauge reads above 3 in. H2O, check for restrictions.

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 ...First, verify engine idle vacuum is around 21 in. Hg (inches mercury). With the engine running and the purge valve solenoid electrical connector disconnected, check for vacuum in the EVAP system - there should be none. If there is engine vacuum, this means the purge valve is stuck open.P144C is most often fixed by replacing the EVAP purge valve assembly (due to the purge valve being stuck open or closed), which can be a little tricky depending on how tight your F150’s engine compartment is. The EVAP purge check valve is part of the Evaporative Emissions System, which exists to control fuel vapor.

The air/fuel vapor mixture continues through the EVAP purge pipe and EVAP purge valve into the intake manifold to be consumed during normal combustion. The EVAP system requires the PCM be able to detect a leak as small as 0.040 inch in the EVAP system. The PCM uses several tests to determine if the EVAP system is leaking.The air/fuel vapor mixture continues through the EVAP purge pipe and EVAP purge valve into the intake manifold to be consumed during normal combustion.
