I just need to know where the purge control solenoid valve is. I know I need to replace it. A picture would be really helpful.
Where is the purge valve located on my 2008 kia sorento
Your local library has online access to most service manuals that you would have to pay for. Many time you can get access to them through their website if you have a library card. If not, go the library and get full free access to all the major car service manuals for free!
Evaporative Emission Control System Purge Control Valve Circuit
What does that mean?
The Evaporative Emissions System (EVAP) allows fumes from the gas tank to enter
the engine to be burned, rather than vented into the atmosphere as an emission.
The purge valve solenoid is supplied switched battery voltage. The ECM controls
the valve by operating the ground circuit, opening the purge valve at specific
times allowing these gasses to enter the engine. The ECM monitors the ground
circuit as well, watching for faults. When the purge solenoid isn't activated,
the ECM should see a high voltage on the ground circuit. When the solenoid is
activated, the ECM should see the ground voltage pulled low, close to zero.
If the ECM doesn't see these expected voltages, or senses an open in the circuit,
this code is set.
Potential Symptoms
P0443 trouble code symptoms could be just an malfunction indicator lamp (MIL)
illumination. There may be no drivability problems at all. But, it's also possible
to have a lean condition or a rough running engine if the purge valve is stuck
open. Usually though, these symptoms are accompanied by other EVAP codes. Another
symptom may be excessive pressure in the gas tank in the form of a "whooshing"
sound when the cap is removed, indicating a purge valve that isn't working at
all or stuck closed.
Causes
To cause a P0443, there has to be a problem with the purge control CIRCUIT,
not necessarily the valve. Usually they are a unit housing the valve and the
solenoid as an assembly. Or it could be comprised of a separate solenoid with
vacuum lines to a purge valve. That said, it could be any of the following:
