Abstract

This relates to a method for diagnosing a sensor for a motor vehicle, and to the vehicle, the method including: a) a step of detecting errors in the measurements taken by the sensor; b) a first phase of commanding the cleaning of the sensor; and c) a step of cancelling the detection of measurement errors by the sensor if the difference between the first variation in the richness level determined on the basis of the parameter relating to the pumping current and the second variation determined on the basis of the variation in the voltage across the terminals of the sensor is: i) less than a predefined maximum tolerance threshold; and ii) greater than a predefined minimum tolerance threshold.
