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.
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
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 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
you need to unhook your negative cable for a few that will reset>
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.
Evaporative Emission Control System control valve malfunction. You need a new evap control surge solenoid valve.
Diagnostic Trouble Code (DTC) P1443 indicates a failure in the EVAP canister purge valve circuit. The Evaporative Emissions (EVAP) Canister Purge (CP) valve controls the flow of vapors from the fuel vapor storage canister to the intake manifold during various engine operating modes. It may need nothing more than a good cleaning, vacuum hose connected or that is leaking, or may need more. I suggest you seek out the services of a good mechanic. Do not just throw parts at this. The code does not mean that any part needs replacing. It just means the EVAP system is being effected.
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.
hi, this code is a manufacture code.. it is for the pruge valve. it is located right by your battery.it has a vaccuum line coming in at the top on one side and one going out on the other side. and a electrical connector on the bottom. ---------------------------------------------------------------------------------------------------------- ***Unfortunately, the P1443 code doesn't point to any one specific part of the evaporative emission system. I had my 96 Ranger to a local mechanic who ran a smoke test on the system. He said it had no leaks, and recommended changing the purge valve or solenoid (the valve located in the vacuum line closest to the charcoal canister). I replaced it (it looked very rusty on the bottom) and yet the code came back. I then replaced the purge flow sensor (located next to the purge solenoid, closer to the engine) and the code has not returned since. The purge flow sensor was bad. There is supposedly another valve or sensor on top of the gas tank in this system, although I could not see it. So, the P1443 code can occur when any of the valves, flow sensor, or vacuum lines fail in the evaporative emission control system.
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.
A P1443 is related to the canister purge system. Most likely you have a faulty canister purge valve and flow sensor. NEW: It happened to mine after i bought if from my neighbor. it was a cracked and busted hose connecting to the canister purge valve. its located on the front right hand side while facing the engine. it looks the canister looks like a black Lego block or battery. the hose connecting to it with 2 valves connecting to the hose were 169 dollars at my local ford dealership which i purchased as a kit to replace it all. it was cheaper than trying to replace the hoses alone. the system relies on vacuum pressure and when the pressure is lost due to a cracked or broken hose or 1 of the faulty valves then it sets off the P1443 code, it killed my fuel economy and performance. once i got the kit, no problems since. hope this helps. sure did me.

????? What do you mean by "code"?
P0402 Exhaust Gas Recirculation Flow Excessive Detected I do not recognize P1443 Instead of throwing parts at the problem, which can be many things. Take it to a professional who you trust, that has the knowledge to diagnose the problem and know what is wrong without guessing. Cheaper in the long run.
