    Default w.b. keeps throwing a code? po1153

    my lc1 wideband keeps throwing a code po1153 after about 40-50 miles of driving. I do notice that the gauge also fluctiates while steady cruising from 14.7 to around 14.1 even under light loads. when the mil light comes on then the lc1 gauge reads a pretty steady 14.6 at cruising. Don't know what's goin on with this? I have adjusted the speeds on the lc-1 as well, with no luck. any suggestions??? here is a copy of my log before the mil light.

    Set P0153 to NO MIL.
    You now have STFT/LTFT data and the NBO2 voltage is not stuck @ .450v.
    What did you do to fix that?

    I had it hooked up wrong.So by setting this to no mil doesn't it still go into "limp mode" or not?

    did you notice on the log the fluctuation in the afr at cruising speed? Is this normal?

    AFR will bounce a little.
    Cut your PIDs down until total channels selected is no more than 24.

    even without logging data on efi live it still fluctuates on the gauge for the lc-1 as it does on the log i have posted. (I bought the gauge kit for the lc-1)

    I'm getting the P1153 and P0154 with my LM-1 too. Apparently you are simulating your narrow band through the controller because your WB sensor is in the NB bung correct??

    Anyway, I thought my problem was the length and quality of the connection. There isn't enough voltage fluctuation because of resistance. My plan is to shorten and tighten the wiring from the controller analog #1 output to the harness O2 sensor weather-pack. Does this sound like your situation?

    yes i have it simulating one side of my narrow band. Although, i did not get a po154 code. let me know if shorting the wires up helps you out at all.

    it was p1153 (insufficeint switching bank2 sensor1) that set the mil light not po153. Should i still set p1153 to no mil?
