My CLT sensor stuck at 82c when it's cold or hot, I have checked the sensor and it's good, check the pin, doing calibrate.

When i unplug the sensor, it's still reading 82c

Any solution?

I think that is typical of not connected - are you sure you have the right board selected and are on the right pin?
have done the calibration?

[GCOM886]

Yes, the board is right, the pin is right, done calibrated

Check the continuity of the two wires from the sensor to the ecu.
One of the cables must have ground from the ucu and the other must have 5v as a reference signal with the sensor disconnected.

I would test both the Mega separately for function and settings, and then with the board, in order to find the source of the issue (Mega, board, settings, etc). Note in the following links, there are tests to voltage (Mega alone) and tests through resistance to ground (board), so don't get confused with which one you are using.

Thanks for the information, among usI will try to figure it out for more. framedKeep sharing such informative post keep suggesting such post.

with a negative coefficient of temperature. These are the most widely used sensors in automobiles. As the temperature rises, their resistance reduces. basketbros

Yes, this is very confusing, thanks for your useful information

Make sure all wiring is properly connected and not damaged. Check for any loose connections or frayed wires.
