    Exhaust Temp Issue's

    I purchased and installed the exhaust temp sensor when i did the tune.

    It worked fine for awhile.

    Now it reads correctly then starts jumping all over the place from correct reading to over 3700 degrees.

    I pulled the sensor out to see if it had something on it or gummed up, but looked fine.

    Any idea's?

    I would check the probe connections where it attaches to the screw terminals and where it plugs into the the MM3 box under the dash.

    If it still reads erratic l would call or email MM3 Power as they supply the EGT probe kits.

    Please keep us posted.

    Like stated check the wire for any damage and the connections.

    Maybe try having someone wiggle the wire as well where possible to see if it happens when they are doing this.
