    ABS codes?

    So my ABS and Traction control light came on pulled the code it says B1227 left rear excess wheel speed variation? So would this just be a bad speed sensor? Little confused because when I did my own research it said it was it was a fuel temp sensor #2 circuit open any suggestions?

    The car does nor have a fuel temperature sensor and even if it did, it has nothing to do with the EBTCM.
    C1227 - Left Rear Excessive Wheel Speed Variation
    That generally means the wheel hub must be replaced, but first you make sure the connector to the left rear wheel is properly connected, clean and dry.

    Put the scan tool away, go to the top of the Eldorado/Seville page, and read the "sticky" thread on how to pull codes from the DIC.

    It has to be C1227. The wheel speed sensor is replaceable separately in the rear, but check the hub assembly for play.

    It is possible for the wheel speed sensor to trigger codes intermittently as it begins to fail. But check the connector and wiring.

    What's the definition of the B code?

    B2719 is my trunk switch not worried about that one I screwed the bolt down so it would close all the way

    ----------

    Yeah it come on every so often and stays on until I park then it won't come back on for a few days to a week

    I plan on checking the connection soon if its the cable do you know a good place to get a new one or would advance auto be good enough?

    So I pulled my codes same as before so I pulled the tire off disconnected the cable and cleaned the connections and plugged it back up. No luck any idea where I go from here? If its telling me (left wheel speed variation) do I just go ahead and replace the bearing? The cable? Or both? I want to take the next step just need a push in the right direction.

    Re: ABS codes?

    Personally I would lean towards the hub & bearing assembly (wheel speed sensor).
