    IMG_7062.jpg IMG_7063.jpg IMG_7057.jpg IMG_7056.jpg IMG_7051.jpg Hey guys,

    I recently bought a 2002 Seqouia and I love it soo much but I ran into an issue recently. A check engine light popped up and when I got it scanned codes P0441, P0446, and P0440 popped up saying Evaporative Emission System. I honestly have no clue what it may be and I need assistance with diagnosing this. When I pop the hood I found 2 suspicious things. A cut cord and a tubeless hole where it look like a tube belongs there. I attached all pictures for reference as well.

    Thank you guys I will wait and standby for any feedback back you have it

    The plug in the brake booster seems odd but I haven't seen under the hood of a sequoia much.

    I'll also assume you have no working coolant temp gauge as that's what the second sensor that's unplugged is for.

    It sounds like maybe your EVAP vent solonoid is clogged or maybe unhooked? Hard to say on that one for sure.

    If you don't get a lot of traffic here stick a post in the 1st gen tundra section.

    The cut plug on MC is one of the pressure sensors M1 and M2 :monocle:
