What does the p0443 Ford engine code mean?
P0443 FORD Meaning. 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.
Why is the p0443 canister purge valve malfunction?
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. P0443 Ford trouble code symptoms could be just an malfunction indicator lamp (MIL) illumination. There may be no drivability problems at all.
Why does my Ford F250 have a purge code?
If your F250 has this code, it is indicating the EVAP purge control valve circuit is malfunctioning.. This is typically caused by a short in the wiring to or from the purge valve solenoid, or an issue with the solenoid itself. Before you do anything, make sure the gas cap is on and sealed tightly.
How to diagnose Ford EVAP purge control circuit?
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.

What causes a Ford F150 purge valve to not open?
Wiring Issues – If the wiring harness from the PCM to the purge valve solenoid is frayed or shorted out, the purge valve won’t open and P0443 will be thrown. Take a look at the wiring harness plugged into the purge valve solenoid and see if it looks undamaged and that it is secure.
