The carbon canister collects evaporated fuel from the fuel tank, where it is stored for later use being pulled into the intake plenum.
Between the evaporative canister & the intake plenum are two devices. 1) Purge flow solenoid & 2) Purge flow sensor. These two devices can, when used simultaneously, test the evaporative system & also meter evaporated fuel vapours into the engine intake under ECU command. 

Basically you either have a leak or a blockage in the fuel evap/ purge system, blow all the hoses with air & check the canister with a vacuum pump if possible. The Purge valve could be blocked even if the solenoid "thumps"; blow through valve while operating the solenoid valve open & closed. Spray carb cleaner into the valve also while doing this. If you put on a new flow sensor I'd assume this to be good, but also associated wiring has to have continuity which could be a a pain to check. You can check the solenoid easily with a bulb. With a warm engine the valve should open intermittently when engine revs rise to about 1500 (bulb will light). Blow out ALL the lines & check the pipe into the intake. I would not blow air into the canister but check with vacuum pump for cracks.

Is fuel tank rusted through anywhere? Also I believe the PCV is connected to the same system.

Here is more info :
Ford On Board Diagnostics II, (OBD II) code P1443 means that the evaporative emissions charcoal canister purge sensor did not detect any flow when the canister should have been purging into the engine intake system. The purging, controlled by the computer,takes place when certain conditions are met, such as engine speed and temperature.What the computer operates to effect this purging is a 12 volt solenoid valve, solenoid means it has a moving piston in it which covers/uncovers ports in the valve so that flow does/does not take place. 

The "gunk" coming out of the charcoal canister will sometimes cause this piston to stick, resulting in purging not taking place when it should, the sensor in the purge hose detects this and sets a fault/trouble code and also turns on the "Check Engine" light. The electrical windings in these valves seldom fail, but anything is possible. To locate and check this valve, first find the charcoal canister, it will be a round or rectangular black plastic "box" with several different size hoses attached to it. If in doubt that you've found it, look at the bottom, there will be a plastic foam filter there---make sure it is not plugged up---.

Once you've located the canister, start following the hoses attached to it. One will go towards the engine, follow that one along until you find the control valve that it attaches to, that's the valve that's not operating. Several things you can do now, just buy a new one and hope it is not the wiring or computer that's at fault. If you want to check it and the wiring, first, with key off, disconnect the two wire connector from it.

Use a 12 volt test lamp, turn the key to "run" and check for current at both wires in the connector, one sould have current. Next, connect the test lamp between the two wires in the connector, start the engine and let it warm up, then run the engine up to around 1500 RPM or so, the test light should come on, if it doesn't, then it is the wire that was "cold" when you checked for power at the connector. or the computer. If the light comes on, then it is the valve. Remove it from the vehicle and clean it with an aerosol can of carburetor cleaner,use the "straw" that comes with the can and spray the cleaner into both hose nipples on the valve, alternately spraying and shaking the valve. 

When you no longer get brown "gunk" coming out of the valve, reinstall it in the vehicle, but leave, if possible, the hose from the canister disconnected. Start the car and let it warm up, (if need be), now raise the RPMs to 1500 or so. valve should now open and a vacuum should be present at the open nipple. If so, the problem is cured. 
On some OBD II equipped vehicles, repairing some problems will cause the computer to turn off the check engine light if the fault is no longer detected, other vehicles require that the computer be interfaced with and the code purged with a scan tool.

When you find the problem it'll be a feeling of some sort of achievement!
Good luck and hope this helps.

Check enging is on---OBD code is PO171 & p1443---how do i fixed this problem


The most likely cause of these two codes tripping together is a vacuum leak associated with the canister purge system. This system collects the vented gasoline vapor from the fuel tank and when the engine is running purges the canister into the manifold.

The P0171 is an indication that the engine is running lean and the P1443 is a fault associated with the Purge Control Valve Solenoid trouble code control valve.

Inspect under the hood for a disconnect vacuum line.

The photos are examples of the vacuum circuit connect via hoses. Listen for a vacuum leak when the engine is running. It would be a whistle sound. Also if work has been done recently look in the area that the work was done under the hood.

Your best to use Google & do your research on internet
for your vehicle description & put in OBD2 Code P1443

Forget the 300 that is just random misfires & most likely
on start up & you don't diagnose that one

Work on the P1443 it will be vehicle specific

Check engine lite came on code is p1443 what does this code mean


P1443 Evaporative Emission Control System Control Valve The Evaporative Emission Control System monitors the fuel vapor flow between the engine intake manifold and the EVAP canister. The system failure occurs when a leak or blockage between the intake manifold, the EVAP canister purge valve and the EVAP canister is detected by the PCM.

Code P1443 Possible Causes:

- Pinched, blocked or plugged fuel vapor tubes/hoses (except between fuel tank and EVAP canister)

- Damaged EVAP canister

- Disconnected, cracked or cut fuel vapor tubes/hoses (except between fuel tank and EVAP canister)

- Damaged EVAP canister purge valve

1996 Ranger-code P1443-"auxillary emmisions controls" is the decription that I got from Advance Auto Parts diagnostic--What can the problem 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. 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.

Codes p0402 and p1443 96 ranger


this means exactly what it says, the emission control valve is faulty and needs replacing.
Basically the valve is in an open position when it should be shut or partially shut.
Replace the valve and this should cure both codes.
