I know that there are some threads in the past about the MTX-L having sensors dying, instead of resurrecting the dead I figured I'd just add my
that I'm another statistic in this.
Car's been out of commission for a month, was getting it back up and running last night, and the MTX-L had lost calibration, so I went to calibrate it and it just sat on "HTR" and wouldn't go to "CAL".
Fortunately my local Advance Auto has the bosch sensor I needed for $40 after 30% off online coupon, so I got up and running right away, but it was more than a bit frustrating (I know it's warrantied, but didn't feel like waiting for the RMA).
The car just sat in my garage, sensor worked great when I parked it, it's mounted in a vertical section of the DP so I know it wasn't sitting in water or anything like that. The unit is 6 months old total, and has been installed for less than three, ran it for about 700 miles, then parked it for a month, and it was dead.
Love the unit, love the gauge, love everything about it.. but if it keeps killing sensors I think I'll get grumpy.
