Abstract

A method of monitoring the operation of a gas sensor is disclosed. A system signal is provided in response to sensing first or second system conditions, and a gas concentration signal is provided in response to sensing first or second gas concentration levels of a gas. In response to the system and gas concentration signals, a signal indicating the operating condition of the gas sensor is provided.
