FMI 0 — Value too high (most severe)
The reading is valid but far above the normal operating range — high enough that the controller treats it as the most serious level of 'too high'.
What it typically points to
A real over-condition (over-temperature, over-pressure, overspeed) or a sensor reporting a believable but wrong high value.
