Check the bayonet temperature probe.  Mine came loose and slide out an inch causing all kinds of goofy readings.

Subject: TSIO 550 temp sensors


I am having temp output discrepancies from one of the TIT sensors so am considering getting a replacement sensor to see if that fixes it. The turbos are Garrett's.

As of last few flights, oil temp feedback is also going sideways.  It's normal during run up and first part of the flight but at cruise it intermittently drops down in to the red arc as low as 40 or 50  degrees and jumps around from there to actual temps.  The problem could be in the wiring or could be the sensor itself.  If the part is not too expensive I would just purchase and install while looking for the cause.  Same is true for the TIT probe.

Can anyone tell me where to purchase and what parts to order?

Thanks,
John
