This SB as issued apples to all engines earlier then 200601. The interesting aspect is that not all engines in this serial number range were equipped with the sensor subject to the SB. If you review the SB and find that your sensor and the diagram do not match don’t be shocked. I talked to Ray Lawerence about this issue and he plans on communicating with UL in hopes of clarifying the SB.
That's exactly what I found.
