Abstract
A diagnostic testing system for a vehicle comprising an oxygen sensor having a heating element for heating the oxygen sensor to its minimum operational temperature, an analyzer having a user interface, a communications link between the analyzer and the vehicle to obtain data from the oxygen sensor, and a diagnostic heuristic analyzing the data and confirming proper operation of the heating element, the diagnostic heuristic being adapted to generate an output and transmit the output to the user interface, the output including the results generated by analysis of the data by the diagnostic heuristic.
