摘要
An exhaust sensor (10) comprises a temperature cell (34/38/36) and a calibration resistor (94). The temperature cell (34/38/36) has a characteristic such that a temperature cell impedance varies as a function of the exhaust sensor temperature, with the temperature cell (34/38/36) having a high impedance at ambient temperature and a relatively low impedance at the operating temperature of the exhaust sensor (10), the operating temperature being higher than ambient temperature. The calibration resistor (94) is electrically connected in parallel with the temperature cell (34/38/36). A method of producing and a method of using such an exhaust sensor (10) are also disclosed.
