I went to get the purge valve assembly. Firts dealer said the number was no good. The second dealer I think found it but didn't have it in stock. I read on hear it's around $100. He gave me a price of $180 that's with discount. I also read you can get it from mazda & it might be cheaper. I tried to call them but they were already closed. Do they sell the assembly too?
Check around with some of the site sponsors on pricing.
I've seen the vapor canister purge valve for around $40 & the solenoid for around $35, so the $180 figure is only a good deal for the Dealer!!!! lol
Did you teat & find a problem with both of them, or are you throwing parts at your P1443 code & hoping for good results????

I replace the hoses from the canister & between the two valve, they were a little dry rotted. That didn't help. I was going to replace the whole assembly since it comes with hoses but after finding out it was like $180 I changed my mind. I guess I will test the purge valve to see if it''s opening & closing. Not sure how to test the solenoid or the thermistor I think Ford calls it. The second valve from the canister.
pawpaw: I payed like $44 for the valve. The o2 readings still show 0 & the fuel trims still show -100. I don't understand that. Besides the O2 readings & fuel trims not showing on the scanner, usually after sitting over night the idle will hunt up & down a few times.
elgato54: I used a 3130, I assume it's volts. I checked the valve manually to see if it would click.

OK, so after you replaced the vapor recovery system purge valve, did you remove the battery B- cable to wipe the computers memory so it can begin to build new fuel trim tables????
I don't understand the lack of O2 sensor readings or the fuel trim figure on your scantool, unless the O2 sensors are kaput!!!!
Will your scantool read the after cat O2 sensor????

pawpaw: I didn't remove the battery cable after replacing the valve. I guess I will try that. I don't understand the O2's & Fuel Trims either. How can I test them with a meter? For the last question I'm not sure exactly what your asking but for all the O2"s that show on the scan toll all show 0 for the reading. Is that what you ment?
Well what I was trying to get at is, if any O2 sensor output on this vehicle can be monitored by your scantool. So if it could read the after cat O2 sensor, it should be able to read the before cat O2 sensors as well.
Seeing as how the scantool will read the Subies O2 sensors, it should be able to read the Rangers also, so it seem to me that bad O2 sensors should be on your suspect list.
You could unplug the O2 sensors & hook up a multimeter on the 1000 Mv range & measure what the O2 sensors are outputting when at operating temp.
With the scantool reading zero output & the screwed up fuel trim numbers, I really suspect the O2 ensors are kaput for some reason!!!!

PawPaw, I have a 97 OHV that I have not been able to read the O2's using the generic mode on my scanner nor my laptop. The PCM will trigger a CEL if the o2's are forced out of range, (propane, induced vacuum, ect)
I can however read all the O2's using the ford extended PID program, and get good reading at the connection at the PCM with a VOM.
Ford never did find the problem, so we live with it.
My Guess, open circuit internal in the PCM to the test port, live monitoring/test problem only.
Thats good input aquanaut20, as their might indeed be a vehicle computer circuit problem. I've not heard of any particular year/model with built in O2 sensor PID monitoring problems, so this is interesting input.
My 95 model Actron CP-9145 scantool, will read the live O2 sensors PID, on my OBD-1, 94 Taurus & OBD-2, 99 Ranger, so I know Fords computers will output a O2 sensor PID for live monitoring.
So if AWC pulls one of his O2 sensors electrical connectors & measures the O2's output, or maybe better still, back probes the O2 sensors lead at the computers under hood firewall electrical connector & measures it's output there with a multimeter, he should be able to confirm that they are switching & it's signal is at least getting as far as the firewall electrical connector & if it is, then it's likely a computer, or internal circuit problem.
Anyway AWC it'll be interesting to hear what you find.
