(98 Altima)
I read what people experienced when this MIL popped up.
Tried the following:
1) Replace gas cap, nothing
2) Checked two solenoid valves near charcoal canister, they're perfect
3) Inspected all hoses that I have visible access to related to EVAP sys,
nothing wrong or rotted or broken.
Does anyone know what else to look for ?
How pressure sensitive is this system? How small does the leak have to
be for the PCM to get pissed and throw the 1440 code?
If anyone has more information, please share it with me.

Maybe someone diagnosed the leak with smoke and can share where
they found it, it may be a common point of weakness/failure on these vehicles.


Thanks a lot for reading !! Thanks even more for posting a reply!
