What causes a p0443 purge control circuit?
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:
How does the EVAP canister purge volume control solenoid valve work?
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 ).
What is the diagnostic code for evaporative emission control?
P0443 is a diagnostic trouble code (DTC) for “Evaporative Emission Control System Purge Control Valve Circuit Malfunction”.
What causes a purge control valve to open?
The ECM has commanded the purge control valve to open and detected either an incomplete open circuit or a short in the circuit. The cause of code P0443 can be a purge control valve internal open circuit or the connector is corroded causing loss of contact with the valve.

What’s the code for the canister purge valve?
Code P0443 deals with two components. The EVAP Canister Purge Control Valve (this video) and the Purge Control SOLENOID valve (video link below). The EVAP Canister Purge Control Valve works with the Canister Purge SOLENOID valve.

What is the po443 code on a 2004 Caravan?
2004 Caravan has a PO443 code. I have also seen 441 and 446 come up at times. It does not have 12 volts at either wire at the purge solenoid with the key on or running. Both wires test as being grounded.
What are the symptoms of trouble code p0443?
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.
What to look for in a Nissan p0443?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. P0443 NISSAN Tech Notes It’s a very common problem with Nissan vehicles.
