How do I fix???

The trick to getting Tone's CD to work is correctly setting the volume label on the disk when you burn it. I think the correct volume label is "vcross00" but don't quote me on that. I'll double check my CD for you when I get home if you want, or someone else can chime in.

As far as overfilling, I let it go until it clicks and leave it at that. I've never had any issues with that charcoal canister, FWIW.

Yeah. Someone's gonna have to chime in about the CD cause the simple intructions from his website don't make sense. "Must burn to CD named same as folder downloaded - VX00ESI1" First off you download a zip "file", not a folder. I named the CD VX00ESI1 and the folder where all the files reside the samd as well. Still not working.

I am still trying to find out if the VX is drivable with this issue, or is my gas tank going to blow up from the pressure?

Your fuel tank won't blow up from pressure, mostly since you'll be removing a volume of fuel as you drive. The charcoal and evaporator stuff is emissions related and isn't necessary, but of course will cause issues just by being there.

After working with Merlin from St. Charles Isuzu, I finally got the issue resolved. Here is the Part and part number that took care of it:

Here’s a summary of the problem for P0446:



“An incorrect fuel tank pressure sensor signal is detected by monitoring fuel tank pressure when the key is first turned "ON" during a cold start. If the fuel tank pressure signal is out of range, DTC P0446 will set. A restricted or blocked EVAP vent path is detected by monitoring fuel tank pressure during normal operation (EVAP canister vent solenoid open, EVAP canister purge solenoid normal). With the EVAP canister vent solenoid open, vacuum level in the system should be very low unless the vent path is blocked. A blockage can be caused by the following condition:

Faulty EVAP canister vent solenoid (stuck closed).
Plugged, kinked or pinched vent nose.
Shorted EVAP canister vent solenoid driver circuit.
Plugged evaporative canister.
If any of these conditions are present, DTC P0446 will set.”



- So, the “EVAP canister vent solenoid” on your Vehicross is located at the rear of the vehicle:



The replacement solenoid includes the ‘filter’ you see attached in the picture. After confirming the vent hoses are not damaged or crimped, you may elect to replace this part. It is Isuzu part #8-97130-368-0, list price $118.69, your cost $100.89.

So I paid a couple dollars more, as shipping was free. Good find though.

Well, stopped by Auto Zone and run my code from the check engine light. P0446. Was wondering whether the part purchased from Marlin solved the problem and whether a non-mechanic type can do this job?
