I don't see any reason why you would need to disconnect first.
As soon as you turn off the car, only the tool will have power.
Without ignition on , the data stops. A
The MX+ will then go into sleep mode after a short time.
You can set the app up to automatically connect when it's launched too.
Kind regards,
Shawn

STFPA 612, FFF
Thank you so much that did the trick it is working like a charm now. 🙏

General OBD Questions / P0446 Code – Any Common Fixes?
« Last post by Alyssa on January 08, 2026, 01:20:27 am »Hi all,
Looking for some advice.
Car is a 2018 Toyota Camry 2.5L, no mods.
Check engine light came on, scanned it with my Autel MX808S and got P0446.
Car drives normal, no rough idle, no fuel smell.
Gas cap looks fine and is tight.
From what I’ve read, it seems related to the EVAP system / vent control, but not sure where to start.
Before replacing parts:
Any common causes of P0446 on Camrys?
Vent valve or wiring usually the issue?
Anything simple I should check first?
Thanks in advance.

« Last post by Shawnf350 on January 07, 2026, 05:11:38 pm »If using the ObdLink app, go to
Settings
User Defined PIDs
Accept the Warning
The top Right menu (3 dots)
Import built in PIDs
Select GM then OK
Scroll down and select "Engine Oil Pressure"
OK
Then see if you can pull the oil pressure data when you connect.
Kind regards,
Shawn
