i have a 1997 3.8 got the p1443 code evap purge valve curcuit malfunction i replaced the evap purge valve and the check engine light is still coming on. i scanned it again with my PDS and the same code is back again. has anyone had this problem and solve it? please let me know

 

Never had it, are you using a laptop error remover and diagnostics software, or a hand held tuner?

 

im using the 2006 ford dealer scanner its labled PDS its basicly a palm piolot with a little module attatched to it in a canvas carrying case

 

Well I seriously doubt that thing will fix the problem. Take the car to Ford and see what they can do, could be an error that has somehow written itself to the ecu, also could be a faulty chip, so just take it to Ford, or to a local shop.

 

i might buy a evap purge solenoid and see if that fixes it. i know several people that work at ford dealers, and they say they replace both the evap valve and solenoid when either of them have trouble. the valve cost 17$ and the solenoid 41$ at dealer cost so naturally i started with the cheapest thing. but i hate just firing parts at the problem.

 

Well best of luck to ya, hope you get that problem fixed, but I would still take it in to get looked at because the best way to get the problem fixed is to have somebody that knows what they're doing working directly on the problem.

 

How did this turn out ?

 

My friends just go to auto zone and they check it for them there, and tell them what the problem is.
And once the problem is fixed, you come back and they get rid of your check engine. . . . [:'(]

 

Thanks

 

it's most likely a vacuum leak or a leaky gasket on the manifold somewhere.

i got the same code on my 98 Isuzu Rodeo and it turned out teo be a broken plastic manifold gasket that was sucking air into #2 port
