摘要:
In a method for detecting the operational readiness of a jump lambda sensor, which is associated with an internal combustion engine, the internal resistance of the sensor is detected as a criterion for the operational readiness of the sensor. The internal resistance is measured by applying a pulsed current to the sensor, the frequency of the current being selected depending on the state of the sensor (1, 2, 3, 4).
