Took the Bobcat with P-60 out to fly today. Start-up was normal and engine responded normally during 7 minute flight. After landing, plugged in the GSU for shutdown and got --Err-- where the temp is displayed. Ran the engine up to full throttle and temp showed 1148 C. Obviously something wrong with temp sensor, at 1148 C there'd be liquid parts dribbling out the back end. Shut down the engine and cucled power to the ECU and RX. Turned everything back on and got "Temp Sense Fail". Did the temp sensor calibration proceedure and after it ran got "Temp Sense Fail - Cable amp".

What do I need to do to fix?

Hello,

The temperature you are seeing is the equivalent of an open circuit on the K type thermocouple, so there is also a chance the black data cable going between the ECU and the front of the turbine is bad. Check that first. If a different cable does not fix it, it sounds like you need a new temp probe.

I believe Bob is letting handy guys change it out themselves but you should call to verify, not everyone is comfortable with that type of repair.

Hope that helps,

Thanks, Matt.
