Underneath air filter container. I had to remove two screws inside the air filter compartment and whose straps that holds it together. Is connected with Evap canister purge solenoid. Advance auto parts or Auto Zone has it.
Means flow when purge not commanded. Bad or stuck purge valve Broken damaged or leaking vapor control system Bad purge control solenoid.
This code indicates an incorrect Evaporative System Purge Control Valve flow. Can be caused by clogged, disconnected, or broken vacuum line between the EVAP Canister Purge Valve and intake manifold or bad Purge Valve itself.
Low purge flow- faultu evap valve or canister.
P0496 = EVAP Emission High Purge Flow Fault -could be a sticky purge valve
next to the evap can on the right side of the car behind the front bumper you will also see the vacuum switch in line with it. as the flow moves it will be the purge valve then the vacuum switch.
My book shows it to mean: Evaporative purge flow sensor fault.
The high purge flow fault in a Chevy Cobalt typically relates to the evaporative emissions (EVAP) system, specifically indicating an issue with the purge valve. This valve, which controls the flow of fuel vapors from the charcoal canister to the intake manifold, may be stuck open or malfunctioning, leading to excessive flow. To diagnose the issue, one should inspect the purge valve, associated hoses, and the charcoal canister for any leaks or blockages. Properly addressing this fault is crucial for emissions compliance and optimal engine performance.
The purge flow is a term used in the evaporation system....or the emmisions system. There is a puge valve that is solenoid controlled. The vapors purge into the intake while the car is running. if you get this code and your gas cap is tight. something is amiss with the fuel system tightness.
What does the word purge mean
The Purge Flow Sensor on a 1996 Ford Aerostar is typically located near the engine, often mounted on or near the intake manifold. It is connected to the evaporative emission control system and may be near the fuel vapor canister. To access it, you may need to remove some components or covers for better visibility. Always refer to a repair manual for specific details on location and removal procedures.
To fix a P0496 error code, which indicates high purge flow in the EVAP system, start by inspecting the purge valve for proper operation. Check for any vacuum leaks in the EVAP system, including hoses and connections. If the purge valve is stuck open or faulty, replacing it is often necessary. Additionally, ensure that the fuel cap is sealing correctly, as a loose or damaged cap can also trigger this code.
The above is copied and pasted from "The Thunderbird And Cougar Owners Club of America" "Straight from the service CD (mostly, I added a descriptor after the code) P1443=A problem with the EVAP purge flow system Continuous Memory Diagnostic Trouble Code (DTC) P1443 indicates an incorrect evaporative system purge control valve flow. Possible causes: -- Obstructed, open or cracked hoses between EVAP canister purge valve and intake manifold. -- Damaged EVAP canister purge valve. -- Damaged PF sensor."
