2006 KIA Optima trouble codes P0444, P0445 Purge control vale circuit shorted, vale circuit open The check engine light is on. I have all ready changed the Purge vale solenoid.


Clear the engine light by removing the battery negative terminal for about 30 minutes. Hook back up and see if it returns. May take up to 100 miles.

2002 Kia sportage with the code p0443


Hi Brittany:
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.

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:
Bad purge solenoid (internal short or open)
Wiring harness chafing or rubbing another component causing short or open on control circuit
Connector worn, broken or shorted due to water intrusion
Driver circuit inside powertrain control module (PCM) is bad

Possible Solutions
1. Using a scan tool, command the purge solenoid to activate. Listen or feel for a clicking coming from the purge solenoid. It should click once, or on some models it may click repeatedly.

2. If it doesn't click with scan tool activation, unplug the connector and examing the solenoid and connector for damage, water, etc. Then check for battery voltage on the feed wire with the key on. If you have battery voltage, then ground the control side manually using a jumper wire and see if the valve clicks. If it does, then you know the solenoid is working properly but there is a problem with the control circuit. If it doesn't click when you manually ground it, replace the purge solenoid.

3. To check for a problem on the control circuit (if the solenoid tests okay and you have voltage to the solenoid) plug the solenoid back in and remove the control circuit (ground) wire from the ECM connector (If you're unsure how to do this, do not attempt). With the ground wire removed from the ECM, turn the key on and then manually ground the Purge valve control wire. The solenoid should click. If it does, then you know there is no problem with the control wire to the solenoid and there is a problem with the ECM purge solenoid driver circuit in the ECM. You'll need a new ECM. However if it doesn't click, then there must be an open in the wiring between the ECM and and the solenoid. You must find it and repair it.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Cheq engine cod. p0440


EVAP emissions control malfunction. EVAP purge solenoid valve faulty.
Check the gas cap first. Try tightening your gas cap a few clicks or might have to buy a new gas cap.

And remember do not "top off" the gas tank when refueling. That seems to help not develop problems in the future.

Were is the evap located on 2001 Chevy s-10 blazer with v6


The EVAP service port is located in the EVAP purge pipe between the EVAP purge solenoid and the EVAP canister. The service port is identified by a green colored cap.

I like to now how to fix the code 0446 on kia optima 2001 2.4l engine. thanks


P0446 - Vent Control of the Evap System. This Evaporative Emissions System is very complicated. These particular DTCs (Diagnostic Trouble Codes) can be caused by MORE than they tell you. Three MAJOR components in the system can cause this P0446. 1. Charcoal Canister, 2. Charcoal Canister Filter, 3. Canister Close Valve, 4. Fuel Tank Pressure Sensor, 5. Purge Control Solenoid Valve, 6, Wiring and/or connector/connections between them and the ECU. If you wish to trust the computer's diagnostics, then replace the canister close valve (after you have inspected the Evap Charcoal Canister's air filter and find no problems with restrictions of air flow). If the problem comes back, check the Purge Control Solenoid Valve and the operation of the Fuel Tank Pressure sensor - either one of those components, if malfunctioning, can cause a P0446.
