摘要： An anomaly diagnosing apparatus and method for a gas sensor which includes a heater control section; a measurement section which outputs a detection signal for detecting an internal resistance of the gas sensor through a solid electrolyte via connection terminals and the electrodes within the gas sensor and which measures the internal resistance of the gas sensor based on a response signal input via the connection terminals in response to the output of the detection signal; and a diagnosing section which heats the solid electrolyte by use of the heater control section, obtains, after the start of heating, a first time required to reach a first resistance and a second time required to reach a second resistance different from the first resistance, and determines whether or not the gas sensor is anomalous by comparing a predetermined threshold value and a ratio of the first to second times.
