Code B0164 Pontiac Description

The B0164 Pontiac code refers to the Inside Air Temperature Sensor Circuit Range/Performance. This code is triggered when the vehicle's onboard computer detects that the signal from the inside air temperature sensor is outside of the expected range or not performing as it should. The inside air temperature sensor is responsible for measuring the temperature inside the vehicle's cabin, which is crucial for the proper functioning of the HVAC (heating, ventilation, and air conditioning) system.
