    Installed JBA headers and check engine light came on.

    Would a 02 spacer clear the code or would I need a tune?

    have all sensors in and have a high flow catalytic converter. 2002 v6

    Don't want to burst your bubble but all aftermarket header minus the TRD are JUNK! Even the legendary DT leak and have fitment issue.

    Stick with the factory. Headers without SC have minimum gain.

    Knowing what the code is will help. Maybe you forgot to connect the front sensor back in after the installation?

    I'm not aware of a spacer for the sensor as our sensor are held in place with 2 nut. They're not like the older version that is screwed on and can use a non-fouler to assist. Plus, there's no tune available that I'm aware of.

    I would start with erasing the code with a scanner than DC the pigtail from the body harness and reconnect.

    -Check the body harness, make sure you didn't pull or damage the connector
    -inspect the sensor connector. Unless you somehow damaged the wires when trying to remove the sensor

    Remains to be seen I bought the tires and wheels the rest came along
    Either just bad timing The heater Circuit quit in the sensor or you damaged the harness in some way.
