According to the 1996 PC/ED Manual, P1443 indicates an incorrect evaporative system purge control valve flow.

Possible causes:

Obstructed, open or cracked hoses between EVAP canister purge valve and intake manifold.
Damaged EVAP canister purge valve.
Damaged PF sensor.

Here's a diagram to assist you in what to check:



Good luck to you.
