The evap control valve is on the cannister
The evap cannister is located underneath the vehicle in front of the fuel tank.
above the rear axel on drivers side
Purge solenoid is on the gas tank along with the evap cannister.
The cannister on my 2002 F150 is located just inboard of the spare tire. If you lower the spare tire it will be easier to access. The EVAP solenoid is also located on top of the cannister. Have fun and don't work to hard. Richard Petty.
P0443 - Evaporative Emission ( EVAP ) system fault - Chilton repair manual P0443 - EVAP Vapor Management Valve ( VMV ) circuit fault - Haynes repair manual P0443 - EVAP Control System Cannister Purge Valve Circuit Malfunction - DTC codes
On the drivers side below battery. From near the front bumper the Evap cannister is connected by vacuum hoses to evap solenoid than another vacuum hose to valve which is than connected to throttle body.
It is that black can looking thing on the left front of the engine comparrment. It has vacuum and eletrical lines.
Trouble code P0449 means: EVAP Vent Solenoid Control Circuit Malfunction
It is most likely one of the hoses to the evap cannister that keeps fuel fumes from going into the armosphere.
Evaporative Emission Control System Incorrect Purge Flow The "EVAP purge flow" faults are issues between the carbon cannister and the intake. The EVAP leak detection generally concerns the fuel tank to carbon cannister plumbing. A little background. The EVAP or evaporative emission system is a control system to keep vapors from evaporation in the fuel tank from getting into the atmosphere. The fuel tank is not vented, but rather the vapors are piped to the carbon cannister (usually located behind the pass. side front wheel) where the charcoal element absorbs the vapor. This is actually a vapor "storage" device. Under certain engine operating conditions, the ECU activates the Cannister Purge Valve (N80) which opens and allows the engine vacuum to suck the fuel vapors back out of the carbon cannister. This purges the vapor, allowing the cannister to absorb more vapor. This evap system has been on vehicles since the '70s. As part of the OBDII standard effective for 1996 cars and newer, it was mandated that leaks in the systems must be detected and reported as a fault which will set the Check Engine Light (CEL). To detect leaks, the system is pressurized by a pump so that leaks can be detected by a lack of appropriate pressure in the system. If there is a leak, such as a cracked vent hose, loose (or leaky) gas cap, poorly installed or defective O-rings on the fuel level senders on the fuel tank, etc. a code will be set. On the cannister to intake side, leaks are detected by deviations in the idle control system. If you have leaks in the lines from the carbon cannister to the intake, intake leaks, a defective purge valve, etc you will often get purge flow faults. My first recommendation is to closely inspect all the small vacuum lines connected to the intake manifold. The corrugated plastic lines are often the culprits, as well as the fabricate covered vacuum lines. Also consider replacing the gas cap.
on the 1996 grand am the evap canister is located on the passenger side, in the fender. would need to remove the coolant reservoir to reach.
