description Methods, apparatuses, and systems for detecting catalytic pellistor poisoning of a gas sensing apparatus including a resistor, a detector, and a compensator are provided. The method includes sampling a voltage reading of the resistor, calculating an electric current value of a gas sensing apparatus circuit based on the sampled voltage reading of the resistor, sampling voltage readings associated with the detector and the compensator for a duration of time, calculating resistance values of the detector and resistance values of the compensator based on the sampled voltage readings from the detector and the compensator, comparing the resistance values of the detector with the resistance values of the compensator, and identifying poisoning of the gas sensing apparatus based on the comparison.
