Various implementations include a vehicle component heating system that includes an electrode disposed within a sensing zone, and a processor. The electrode generates heat for a surface of a vehicle component within the sensing zone and senses proximity of an occupant to the sensing zone. The processor selects a heating percentage of a duty cycle for generating a heating signal, a sensing percentage of the duty cycle for generating and measuring a sensing signal and reporting the measured sensing signal, and an idle percentage of the duty cycle during which neither the heating nor the sensing signal is generated, wherein the sum of the heating, sensing, and idle percentages is 100%. The processor generates the heating signal and/or generates and measures the sensing signal and reports the measurement of the sensing signal based on the selected percentages.
