A method and apparatus for measuring the O2 content in an exhaust gas of an internal combustion engine by exposing two resistors to the exhaust gas of an internal combustion engine. The resistance of both resistors varies as a function of the temperature of the exhaust gas to which it is exposed. However, the resistance of one of the resistors also varies as a function of the oxygen content of the exhaust gas. Therefore, an electrical signal can be obtained which is a function of the O2 content of the exhaust gas, with the temperature effect of the exhaust gas on the resistor being minimized or eliminated. |
