Sensor definitely defective?

Hi.

I actually wanted to check if the motor had just started a regeneration cycle, and I took the opportunity to create another "start log" using a different battery.
I noticed something strange in the log.

(Background: Approximately 14 km driven, regeneration has been running for 485 seconds, the vehicle was just parked to retrieve a laptop.)

Is it clear that the sensor is broken?

The timeline is not labeled.

Sure, blame it on Excel.

You can tell when the process starts by the increasing voltage.
The entire log is 30 seconds long.

The jump from 50 degrees to 89 degrees occurred within 70 milliseconds.

It could also be a loose connection with a contact resistance. But I would still start by replacing the sensor.

Are you sure it's 90°C? Since the engine was running before and only stopped for a short time?

Okay, Excel has been conquered, and a scatter plot has been implemented.

Yes, those 90 degrees are definitely correct.
I've now also reviewed all the other logs containing temperature data, and they are all fine.
It was a huge coincidence that I saw the jump.
