Something wrong with replacement filler neck?

[ohsoferrety]

Hi! I'm new around here, I'm that car-savvy, and just need a little advice.

My father gave me a 2001 PT Cruiser. It's a beauty. When I got it, the 442 error code came up. I replaced the gas cap, but it still came up. I took it to a mechanic, who also just told me it was the gas cap. It wasn't, of course - it was the filler neck. After two long weeks of running back and forth to his shop, he replaced the filler neck. However, now everytime I go to get gas, the pump does that "popping" thing to say that the tank is full...but it's not. I ran the car down to E, went to fill it, and it still did it. Is this a problem he caused, or just a kink that needs to be worked out with the new filler neck? Thanks!

I have a 2001 since August 2000 and it's been doing that since new. Only if I go extremely slow while filling, or just keep putting gas in when it cuts off do I get it completely full. I did notice that certain pumps at particular stations are worse than others. Putting the pump handle further in or out doesn't seem to help either. Waiting a second so the gas settles and fumes dissipate when it clicks off does seem to help a little.

Here's some information to read also ........

I've had problems with that code on my 03 GT Cruiser. The first time, a couple of years ago, I replaced the gas cap for a cure. A couple of months ago the same code came up again. This time instead of replacing the cap, I greased the cap threads and filler neck seal with silicone grease which fixed the problem.

Most likely when the mechanic replaced the filler neck he pinched or left the vent hose clamped closed.

442 error code likely means one or more problem, such as a loose or improperly affixed gas cap, a small leak or hole in the fuel vapor hose or tube, leak in the evap system and a faulty fuel filler neck. the basic repair is to remove the gas cap, clear the codes and drive for a day. see if the code comes back.

A blocked or pinched off vent tube will cause the fueling problem, it can also cause the P0442 code on some of the Chrysler vehicles.... WHY? I don't know. It's run me around a couple of times.
