A lot of times, the cam sensor gives out reading. And for as long the reading is within range, PCM sees it as "operating within normal parameter". The problem that most Nissan vehicles experience is that the voltage and resistance of the sensor so fluctuates erratically that the result of the PCM trying to compensate is shown as "gas, no gas, more air, oops, less air, gas, more air, less gas, ." You get the picture. That translates to the car bogging down, won't go faster than certain speed. And as far as the PCM goes, it sees the cam sensor works within its range.
You don't have to buy a new one just yet. You don't even have to pull it out of the bell housing. Just check the voltage of the connector. I am not at home, so I don't have access to the specs. The older SR20DE spec is 5.0 volts on the connector, and the resistance is within 166 to 204 ohms.
If the specs are out of range, you will get codes for cam sensor, usually P0010 through P0025. Wait a minute. You do have P0024. That stands for "B" Camshaft Position - Timing Over-Advanced or System Performance (Bank 2). I just noticed that. There, you have just diagnosed the problem.
