    I have a 2011 Taco. I also have an UltraGuage from that era, getting it in late 2011.

    Right now it's reporting the following Trouble Codes:
    P014M, P014N

    The problem I'm seeing is that these codes seem to be related to the O2 sensor (P014), but I cannot find the M or N designation. I was under the impression that these numbers were HEX, i.e. 0-F, so I have no idea what M and N actually means, and neither does anybody else on the Internet. So, what gives?

    Notwidthstanding, do I have to replace the O2 sensor? I understand I need a special wrench to do so.

    Thanks for your help.
    Cheers,
    -Polar

    Only person I could find mentioning it is @cliffyk
    Is there an actual Engine Light on?
    Or is it a pending code?

    It's not reading the codes properly. Try a different reader.

    yeah, it first started at pending code, P014M, P014N, and then the Trouble Codes registered and the Check Engine like came on.
    Strangley, also, the light underneath the Check Engine Light, which looks like the Slip Differential light came on as well.

    I have used the UltraGauge to turn OFF the Check Engine light, and the Slip Differential light goes off as well. I've done this twice, and the Check Engine light and the Slip Differential light comes back on after a whlie.
