This code indicates an incorrect Evaporative System Purge Control Valve flow. Can be caused by clogged, disconnected, or broken vacuum line between the EVAP Canister Purge Valve and intake manifold or bad Purge Valve itself.
Follow the troubleshooting tree that is associated with that code.
you need to unhook your negative cable for a few that will reset>
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
My book shows it to mean: Evaporative purge flow sensor fault.
I had my check engine light come on in my 96 T'bird and I stopped at Autozone to get it checked. I got the P1443 error as well, and it said probable causes were: 1. Failed EVAP pressure sensor 2. Blocked hose between purge valve and FTP sensor 3. EVAP purge valve stuck closed I have read from others that say it could be just a cracked hose as well.
P1443 Evaporative Emission Control System - Vacuum System - Purge Control Solenoid or Purge Control Valve fault Loose or defective gas cap will cause this code.
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
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.
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.
Check on the driverside cylinder head. My engine code is on the head.
When the check engine light comes on it should post a code. Use a code reader to see what the code is and ask again.
