ABSTRACT:
A diagnostic testing system for a vehicle includes an oxygen sensor, an analyzer having a user interface, and a communications link between the analyzer and the vehicle to obtain data from the oxygen sensor. A diagnostic heuristic is used to analyze the data and confirm proper operation of the sensor; and an output is generated by said diagnostic heuristic to the user interface.
