Thread: 2000 dakota r/t JTEC+ o2 enable/disable not working?

    2000 dakota r/t JTEC+ o2 enable/disable not working?

    i'm catless on my dakota r/t

    i tried the o2 sensor by itself in the exhaust, and the cel light went off for a little while and then came back on.
    i tried the spark plug anti-fouler trick, light went away a couple drives later then came back a couple drives after that.

    in HPT when i try to disable the secondary o2... it still throws a code?

    i haven't updated my HPT software in a while... is there more support / functionality for JTEC+ now?

    i can't get the light to go away... maybe a o2 resistor trick to fool it???

    which codes do you have coming up as im running catless on my 01 truck and i recommend not updating vcm editor as they have locked out the ability to modify to codes needed for running catless if you already have to codes disabled then they will stay disabled but you wont be able to edit them after you update the software.
