If you had O2 sensor problems, the car would throw up an engine malfunction code.

You could try disconnecting the battery overnight to reset the ECU and emissions data. Run the car for a week of mixed driving and then retest. The test station should give you full info on what caused the fail. I would go somewhere else.

This is a emissions test cycle;

The cycle simulates an urban route of 12.07 km (7.5 mi) with frequent stops. The maximum speed is 91.2 km/h (56.7 mi/h) and the average speed is 31.5 km/h (19.6 mi/h).
The cycle has two phases: a "cold start" phase of 505 seconds over a projected distance of 5.78 km at 41.2 km/h average speed, and a "transient phase" of 864 seconds, for a total duration of 1369 seconds.


The dirty secrets of vehicle emissions testing

Hi Rob:

The crankshaft os part of the engine that rotates when the engine is running, so if the engine runs, the crankshaft will be turning.

The reason the belt is burning through is that someting else must be seized. With the belt off, EVERYTHING that the belt touches MUST be able to rotate. So, check the water pump, alternator, AC pump, tensioner, Power steering pump. You'll find it.
