error code p1443
my dad just got a 1996 ford escort wagon with a 1.9L, and since he bought it (private party) he's had a MIL light on, we had the code scanned at autoone and we got a code P1443, Mfg. Specific Auxillary Emissions Control.... of course when I called a Ford service department about it, they gave me the usual spheel "Blah blah, you'd have to bring it down so we can scan it, blah blah".... no, I'll pass on being charged $80+ for what autozone already did for free......... so, my question is, what the heck can cause that specific code, what should I be looking for?

RE: error code p1443
My grandfather's 97 escort wagon has the same error code. Does anyone know what & where the emissions thing is????

RE: error code p1443
there is a reason they want to scan it so you can be accurate you cant look at all codes and tell exactly what the problem is the best test for this is a smoke test
HX45 DTC P1443 and P0455: CHECK FOR EVAPORATIVE EMISSION SYSTEM LEAKS
Note: When checking for leaks or blockages in the EVAP system, energize (close) the canister vent (CV) solenoid through the scan tool for a maximum of nine minutes per pinpoint test step. Then de-energize the CV solenoid prior to performing the subsequent pinpoint test step. This is done to assure proper closing of the solenoid.
Disconnect and plug the EVAP return tube (EVAP canister purge valve to intake manifold) at the intake manifold vacuum source.
Connect scan tool.
Key on, engine off.
Access VPWR PID. If the voltage is not 12 volts or greater, GO to HX61 .
Locate evaporative test port [marked EVAPORATIVE SERVICE PORT DO NOT USE UNREGULATED PRESSURE ABOVE 6.89 kPa (1 PSI)] near EVAP canister purge valve or EVAP canister.
If vehicle is not equipped with the evaporative test port, GO to HX50 .
Install the Rotunda Evaporative Emission System Leak Tester 310-F007 (134-00056) or equivalent at the evaporative test port.
Close CV solenoid by accessing Output Test Mode on the scan tool.
Select ALL OFF mode and push START button.
Regulate the nitrogen or argon gas pressure on the tester to 3.48 kPa (14 in-H2O).
Follow the instructions that come with the EVAP System Leak Tester and pressurize the EVAP system.
Perform the EVAP system leak test.
