I don't think you are talking about the Crank Position Sensor, you are talking about the Crank Fluctuation Sensor.

If you are savvy, you could navigate the DMV regulations and see what it would cost to get the OBD2 put on the rollers (assuming you would pass that way.) Also some states have a waiver for emissions altogether if you spend XX amount of money on the car and don't get it to pass emissions.

You might be able to buy a shiny new exhaust and have that count towards the money,
