Okay, so my CEL came on with the typical P1443 code on my '95 2.3 5speed 4cyl with 135k on it. I replaced the PCV valve and the Cannister valve assembly (the whole assemby: Ford Part # F57Z-9C987-AB). MY CEL is still on! I took it for about a 10 mile drive and it won't shut off! The only thing I can think of what that I didn't disconnect the negative battery cable when replacing the parts. Could that have something to do with it? HELP!!!


Thanks!

Dave

 

DTC P1443 indicates an incorrect Evaporative System Purge Control Valve flow. This can be caused by a clogged, disconnected or broken vacuum line between the EVAP Canister Purge valve and the intake manifold as well as a bad EVAP Canister Purge valve itself..


Is the gas cap on correctly?
