ABSTRACT:
A gas sensor (8) includes a body (10) that is shaped to define a chamber (14). An electrolyte (34) is contained in the chamber (14) and three electrodes (26, 28 and 30) that are located on an electrode substrate (24) are disposed in contact with the electrolyte. The body (10) is electrically connected to the three electrodes. A cover (36) engages the body (10) to enclose the chamber (14). A resistor array (58a-58n) is located between the cover (36) and the electrode substrate (24). The resistors (58a-58n) are coated with a compound that emits a predetermined gas in response to temperature increase. To test the sensor (8) voltage is selectively applied to the resistor array (58a-58n) to introduce the gas to the gas diffusion path of the sensor (8).
