Air flow sensor chip-heating control device and method of diesel hybrid electric vehicle

An air flow sensor chip-heating control device and method of a diesel hybrid electric vehicle controls whether an air flow sensor installed in an engine intake system of the diesel hybrid electric vehicle performs a chip-heating operation. Particularly, the air flow sensor chip-heating control device performs a chip heating operation of the air flow sensor based on a result obtained by deciding a driving history of an engine when the vehicle enters into a hybrid mode during driving of the engine.
