On my 96 escort 1.9 I have a code P1443 Auxiliary emission controls. What emission controls would this be? The egr valve? O2 sensor?
P1443 - Very Small Or No Purge Flow Condition A fuel tank pressure change greater than a minus (-) 7 inches of H2 O in 30 seconds has occurred with purge (fuel vapor) flow less than 0.02 pounds per minute. Blocked fuel vapor hose between EVAP canister purge valve and FTP sensor.
Blocked fuel vapor hose between EVAP canister purge valve and engine intake manifold.
Blocked vacuum hose between EVAP canister purge valve-solenoid and engine intake manifold.
EVAP canister purge valve stuck closed (mechanically).
Check for blockages between the fuel tank, EVAP canister purge valve and engine intake manifold. Check obstructions in the EVAP canister purge valve diaphragm and ports.

all OBD-II codes w/ explanation can be found here : http://www.feoa.net/modules.php?name=Fo ... c&p=299849
