Temperature sensor fault

What does A30920 mean?

An error occurred during the evaluation of a temperature sensor connected to the power unit. This can manifest as a wire breakage or a disconnected sensor (e.g., KTY: R > 2120 Ohm) or a measured resistance that is too low (e.g., PTC: R < 20 Ohm, KTY: R < 50 Ohm). Accurate temperature monitoring is crucial for protecting the power unit from overheating. If unaddressed, this could lead to undetected overheating and potential damage to components.
