The sensor thingy is the oxygen sensor.. Yes you can run a car without it. The problem is though when the car goes into closed loop mode in the ecu it needs the o2 sensor to read the levels in the exhaust to adjust the fuel mixture. A car goes into closed loop mode whenever you crusie at a constant speed or gentle accelerate. If there is no sensor then the car will compensate and add more fuel on the nissans as a safety factor. which means you get bad fuel economy and horrible smoke from it running rich everytime you step on it.
If you have ever been in a car with a air/fuel ratio guage you know that it has reached closed loop mode once the lights on the gauge move backwards and forwards at a constant pace like the light on front of knight rider.
