Not unless the catalytic converters were changed or have been damaged/degraded. The O2 sensor is still in place and the exhaust past the cat has nothing to do with emissions.Yes, sensor could be bad. Read the manual again. The test you did was for the heater, not the actual sensor. There are 2 circuits in the part. One that gives O2 readings, and one for the heater. The heater is only there to help get the O2 sensor working faster from a cold start; once the sensor is hot enough, the heater is not needed. If the heater were completely dead, it would just take longer for the sensor to give O2 readings, but there would be no effect on emissions as long as the sensor was hot and working. It's difficult to test the actual sensor is working on OBDI cars.Not sure what to say. I honestly don't know how much of an effect a bad O2 sensor or a mis-timed belt would have. This kind of info isn't easy to come by.
