2 most likely causes:

- Leak or blockage in the network of hoses between the carbon canister and the intake manifold.

OR

- Failed Purge Flow Sensor.



The Purge Flow Sensor is a common problem for 95~97 Rangers. When it fails, the PCM gets bogus flow rate data and that can cause the P1443.

Ford sells the PFS as part of a larger hose/valve assembly that goes for well over $100. If you do decide that the PFS is all you need, it is available alone as CP416 from www.RockAuto.com for around $20 + shipping.

how can I be sure that's bad? All the hoses seem to be good, I ha it running and sprayed carb clean over a bunch of vac lines and the rpms never changed

because there is only vac there when the PCM commands it

Although when the rpms are 2k or higher I hear a whistle but can't tell where it's coming from

You can't say for sure that the PFS is bad. There's no field test that you can do to check it. However, if you can eliminate leaks and blockages in the system as a cause and you have already replaced the Purge Solenoid, there isn't anything else left but the PFS. Fortunately, it's not that expensive through RockAuto, at least when compared to many other emission parts.

Here's a generic diagram showing the canister purge from the 95~97 era:

ok thank you very much! Tommarro I'm going to check the line that runs to the fuel tank and see if it's bad

The line from the fuel tank to the canister is important for some fault codes but it has nothing to do with P1443. P1443 just says that the PCM has compared open and closed purge flow rates using the Purge Flow Sensor and that the PCM detects low or no flow.


Heads up: Many aftermarket parts stores and sites incorrectly identify CP416 as the Canister Purge Valve (or similar name) when it is actually the Purge Flow Sensor. The PFS uses 3 wires and the Purge Valve uses 2 wires. They are shaped differently as well.

(The correct SMP part number for the Canister Purge Valve is CP403 - If you look it up on RockAuto, its picture should look like the part that you already replaced.)

I have used a CP416 PFS sourced from RockAuto to correct a P1443 code. It came in a Standard Motor Products box but the part inside was embossed with the Ford oval logo. If you replace the PFS, be sure to install the new part in the same flow direction as the original.

well I've replaced the purge valve is there any way I have it flowing back wards?

I had to replaced those! I did the sensor then the solenoid and it was the solenoid.

It is basically an on/off valve but I suspect that it should be installed the way the factory did it. There is slight difference in the port layout and that may be to avoid having engine vacuum either pull the valve open or closed. Just a guess though.

I would refer to the drawing above and make the ports look like that. Or you could look at another 95~97 Ranger.
