The present invention provides a self-heated pressure sensor assembly and method of utilizing the same. The self-heated pressure sensor assembly regulates and maintains the temperature of the pressure sensor, regardless of the external temperature environment, without an external heater as in prior art embodiments. Exemplary embodiments of the pressure sensor assembly incorporate a resistance heater that is built into the sensing chip of the pressure sensor assembly. The pressure sensor assembly also utilizes the resistance of the pressure sensing elements to monitor the temperature of the assembly, which works alongside the resistance heater to maintain a stable temperature within the pressure sensor assembly.
