EMS- lost signal on #1 EGT

[pgtuck]

Two year old fully functional Dynon complete panel system is RV6A. Last week #1 EGT stopped working. #1 EGT read out has a red X on it. Absolutely no data. The attached picture is from the EMS setup menu.

Replaced #1 EGT with new sensor. No change!
Anyone have Thoughts on possible resolution? Thanks in advance!

Replace the spade connectors. This is the problem more often than a probe going bad. You can get them at Aircraft Spruce or Stein:

Pidg Faston Receptacles By Amp | Aircraft Spruce

Pidg Faston Receptacles By Amp *Style A: Has no dimple with wire stop.

RED Insulated Fast-On Terminal for standard aircraft wire - Steinair Inc.

RED insulated 22-18awg 1/4" series Fast-On QD receptacle crimp Terminal. The terminal accepts a 1/4" wide x 0.032" thick tabs.

If memory serves, you want the 1/4” wide spade.

The wires are thin so I typically add a #22 wire along side the probe or EMS wire to fill in the connector.

Thanks for your reply. Already replaced connectors plus pulled wires from D-sub connector and, replace new D-sub pins. Open to any and all ideas!

I had the same problem 2 years ago: I changed 2 sensors to no avail ...
I then solved only by changing all the engine wiring, 912 and Sport, as a badly tightened clamp had caused damage to the cable due to unwanted vibrations. The wiring was poorly installed by the manufacturer ...
