    So Thursday of last week I installed the TRD Pro grille and TSS relocation kit on my 2018 SR Tundra. Friday I unhooked my battery for about 30 minutes to pop off my driver side pillar cover to see about wiring up some lighted vanity mirrors, but never actually touched any of the wiring. Drove the truck later that night and no issues. Everything was fine until Saturday when my check engine light came on. I was able to use my brother's OBD2 reader tonight and got the following codes.

    I'm hoping this is just a coincidence and I didn't screw something up by unhooking my battery or messing with the TSS sensor. I figured I'd ask here before taking it to Toyota and they blame me for messing with stuff and thus voiding any warranties. Anyone know what could have caused this problem?

    The common areas cause this issue that you can refer:
    - emission canister or fuel tank leaks
    - Missing or loose fuel cap
    - Connector/Wire Harness (canister pump module - ECM)
    Hopefully it can help you to narrow down the things you should take a look.
