Code P1443 is idle air Control (IAC) valve Speed fault
P1443 EVAP System - Tank Cap Missing Mostly it may be damaged. usually appears with code P0455
The p1443 code means a problem with the evaporative emissions system. There could be a problem with a broken or unhooked vacuum hose. Also could be a problem with the solenoid or sensor between throttle body and evaporative canister.
My book shows it to mean: Evaporative purge flow sensor fault.
Follow the troubleshooting tree that is associated with that code.
The above is copied and pasted from "The Thunderbird And Cougar Owners Club of America" "Straight from the service CD (mostly, I added a descriptor after the code) P1443=A problem with the EVAP purge flow system Continuous Memory Diagnostic Trouble Code (DTC) 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."
P1443 code evap emissions control malfuction no voltage at solenoid.
Trouble code P0118 means: Engine Coolant Temperature Circuit High Input Trouble code P1443 means: Evaporative Emission System Control Valve (low/no flow) Trouble code P0301 means: Cylinder 1 Misfire Detected Trouble code P0306 means: Cylinder Number 6 Misfire Detected
you need to unhook your negative cable for a few that will reset>
p1443 is an evap probleem. check hoses between evap cannister and intake manifold. look for leaks, cracks, broken, etc etc hope this helps. also type code into google and do some quick research. hope this helps. good luck . S. San Diego, Ca
Evaporative Emission Control System control valve malfunction. You need a new evap control surge solenoid valve.
The code P1443 for the 1996 Ranger means that there is a problem with the EVAP Pressure Sensor. The real culprit might be the Vapor Canister Purge Valve since the EVAP Pressure Sensor rarely fails. The VCP Valve is around $60. Before purchasing this part, check all hoses around it for leaks.
