Mine reads around 40 degrees too cold.
I replaced the sensor in front of the radiator yesterday,still way wrong...nothing changed.
What else could it be?

What year is the car?

It does take a while to refresh. Drive around for a few days in varying conditions and check back in.

There isn't a way to calibrate it as far as I'm aware. The sensor itself is just an analog thermistor, so the ECU takes the analog voltage from the sensor and converts that into a temperature reading.
