Like the title says I have had a p1443 code that won't go away. I have replaced the purge valve, sensor, all the vacuum lines in between, filler neck and gas cap and still have the code, only thing I haven't looked at is the charcoal canister but don't want to keep throwing parts at this. I'm stumped and am tired of the check engine light staring me in the face.

If you have replaced all the hoses and the purge valve I would start looking for connector issues, like corroded terminals or frayed wires in the connector that snaps on to the valve. Sounds like you did your homework otherwise.

I went ahead and bought a new charcoal canister from rock auto today. I'm beginning to think it's the culprit now. I don't think I've been getting a complete full tank of gas for awhile cause my mileage has gone down a bit now and the filler neck has been replaced and I have relatively new spark plugs, air filter, and fuel filter.

future reference for following members..

DTC P1443: VISUAL CHECK OF EVAPORATIVE EMISSION SYSTEM

Continuous Memory Diagnostic Trouble Code (DTC) P1443 indicates an Evaporative emission control system or evaporative canister purge valve (mechanical) malfunction.

Possible causes:

Damaged EVAP canister.

Pinched, plugged, blocked, cracked, cut or disconnected fuel vapor tubes/hoses between the fuel tank, EVAP canister, EVAP canister purge valve, purge flow (PF) sensor, and the engine intake manifold.

Damaged EVAP canister purge valve.

Damaged PF sensor.

EVAP CANISTER PURGE, or PF circuit shorted to VPWR.




EDIT: Found this on another site.

"Less than two months ago, I purchased a used 1997 Ford Ranger XLT, Regular Cab (2.3 L I-4, 5 spd.). Shortly after the purchase, the check engine light came. I had the code read at a local auto parts store, and the code P1443 was returned. The description for the code was “Evaporative Emission Control System Control Valve”. Initially, I didn't do anything to fix the problem. The light ended up clearing itself a couple of days after it first came on. However, the light only stayed off for a few driving cycles before it came back on (and stayed on). I had the code read again, and again I got the P1443 code.


I did some research on the web and found that the problem could be the Canister Purge Assembly. This assembly connects the intake manifold to the charcoal canister and the assembly is made up of hoses, a valve and a sensor. On my 1997 Ranger, it is located near the front of the engine compartment on the driver's side (the canister is right behind the driver's side headlight). Apparently, if there are any cracks in the hoses, or if the valve or the sensor wears out, this will cause the check engine light to come on, and return the P1443 code. After looking around on the web for a couple of days, I was lucky enough to find a few part numbers for the canister purge solenoid/flow sensor assemblies:"

F57Z-9C987-AB Canister Purge Solenoid/Flow Sensor
Assembly - 2.3L

F57Z-9C987-CA Canister Purge Solenoid/Flow Sensor
Assembly - 3.0L

F57Z-9C87-BA Canister Purge Solenoid/Flow Sensor
Assembly - 4.0L
