1. A method for assessing an output of a temperature sensor, comprising:
generating an estimate of a temperature of a sensor coupled to an exhaust gas passage based on an engine coolant temperature and an ambient air temperature; and
indicating whether or not the temperature sensor is degraded in response to the temperature of the sensor.
