D180K EFIS Sensor replacement

[Shlips]

Hi. New member here. We have an issue with a Skyview D180K fitted to our P&W R985 radial engine. We are the second owners after the aircraft was modified and required.
We get multiple warnings on CHT and EGT, as well as Hi Voltage messages. I suspect this is related to some of the sensor probes becoming unserviceable. Is a common problem over time or with radial engines? Easiest way to replace or buy probes? Thank you

CHT alarm and Hi Voltage alarm.

The CHT goes from hi to cold randomly as does the Hi Voltage. All analogue original gauges show normal readings so I suspect the probes need replacement.

I would like to know which probes are best for the radial R985
