So you're getting a P0443 rather than the subject P0433?
P0443, according to the factory service manual, indicates a failure in the EVAP canister purge valve circuit.
Possible causes:
-- VPWR circuit open.
-- EVAP canister purge valve circuit open.
-- EVAP canister purge valve circuit shorted to PWR GND.
-- EVAP canister purge valve circuit shorted to VPWR.
-- Damaged EVAP canister purge valve.
-- Damaged PCM.
Were you bench testing the valve (wiring battery voltage to it), or testing for flow under PCM control?
