Keep getting a PO440 code coming up after the swap. Minor but annoying. I noticed that one of my VSV's was "ticking" one day. I didn't notice which one.

I thought I recalled reading about someone with a similar problem but I can't find the thread now. I haven't really done any troubleshooting yet other than testing the gas cap (which is fine).

Anyone have a similar issue that can give me an idea what it might be. Thanks in advance.

 

Do you have the FSM to help with the troubleshooting?

 

I have a Haynes manual and some downloaded FSM's. The downloaded ones are a bit of a pain to navigate unless you know exactly what you need.

I think I have another Vapour Pressure sensor in my toolbox somewhere. I'll try switching that out and see what happens.

 

You ever get this figured out Neoworm? I'm getting, po441, and po446 twice every once in awhile. Got a new gas cap and this last time po440 showed up twice, too. Also, having trouble remembering, you used the 3.0 canister, right?
