To cause a P0443, the problem exists within the purge control circuit, not necessarily in the valve itself. Any one of the following can cause the code to be thrown:
-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
Solution sets:
1. Use a scan tool to force the solenoid to activate (you will need a good scanner, not just a trouble code reader). 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 when trying to use a scan tool, unplug the connector and examine the solenoid/connector for damage, water, etc. Follow this with a voltage check on the feed wire with the key in the on position. If there is voltage, ground the control side manually with a jumper cable; if it clicks the solenoid is working properly, but the control circuit is not working properly. If there is no click, then replace the 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 the problem is in the ECM purge solenoid driver, and the ECM needs to be replaced. However if it doesn't click, then there must be an open in the wiring between the ECM and and the solenoid. Find and repair it.

I have a truck that popped up a P0443 code up and I've been trying to see what it is so I can get it fixed thank yo


P0443 - Evaporative Emission Control System Purge Control Valve Circuit Malfunction

Possible causes: - Faulty Evaporative Emission (EVAP) Purge Solenoid Control
- Evaporative Emission (EVAP) Purge Solenoid Control harness is open or shorted
- Evaporative Emission (EVAP) Purge Solenoid Control circuit poor electrical connection

When is the code detected? An improper voltage signal is sent to Engine Control Module (ECM) through the valve.
Possible symptoms: - Engine Light ON (or Service Engine Soon Warning Light)
P0443 Description: The Evaporative Emission System (EVAP) canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the Engine Control Module (ECM). The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.

I have a 2001 dodge ram 1500 code P0443 code came on code p0455 code was on I replace the purge valve then the code p0443 came on


code p0443=It's whining about the control circuit for the purge valve. Make sure you are getting power to the valve, and you see 12 volts on the control side as well.

code p0445 might be just a gas cap problem.

I have a plymouth neon and need to find out how to fix code p0443


P0443 Code is purge control valve circuit. Go to the driver side near the battery or better yet use the underhood sticker emission diagram That black cylinder is the canister,on it is the purge valve which hoses lead to the intake. make sure the hose are not torn,or leaking or disconnected if it is clear the code rerun the monitor (just drive it its 2 trip),because more likely that would be the code for P0443.Just because its a valve circuit doesnt mean its the valve circuit the ECM sent a command to purge and the MAP did not detect a purge,The ECM doesnt know if it is caused by a bad purge solenoid a disconnected line for the purge (normally closed) so it coded it if you want to fix it it is either the hose of the purge or the valve itself.
