    Ever seen flex sensor wig out and read way high content middle of a pull?

    Ive seen bad connections have the reading DROP OUT and show intermittent low, but never magically high readings like in this log?

    I have seen it read high when shops install the sensor on the return side. Is the sensor on the return line?

    I just replaced the sensor, even though it normally seemed to work fine, and have not seen the problem reoccur. Yet.
