Low EGT Reading from Cylinder 2 during Descent

I have the same problem and it appears to be the sensor going bad. Try moving the sensor or tightening the clamp but they do go bad. mine actually went to zero but all other temperatures were normal and running normal. I would think a low temp would also be lower on the cht?

High temps would be more of a worry

Thanks for the reply. May i understand how does the sensor going bad cause the EGT reading to repeatedly drop from 600+ deg C to below 400 deg C during descent, and recovered back to operating range when leveled off?

You might try swapping adjacent sensors, to see if the problem moves with the sensor or stays with the cylinder...

I tried replacing the EGT sensor of cylinder 2 but the problem still persists. Could it be the carburetor that is causing the problem? The problem seems to surface only during descent. 

I am having the same problem. We checked float weights a few weeks ago and had to replace the left carbs floats.Ever since in decent the right side egt will flash that the is no temp.or low and then will be ok after landing. Have replaced the dynon prob. Still did it Swapped leads, it followed. Just replaced with another new prob, haven’t flew it yet to test. I saw this post and thought if anybody had a idea?
