Default Question about p0320 code

So my question is what sensor is it? I have 2001 PT cruiser le 148xxx miles. It died while i was driving. After about 20 minutes it would again. A friend got me the cam and crank shaft sensor. But it was after market parts. So it died and would not start again. Took a chance put the old parts back on and now it will start. Lol Just scared to drive it. Don't want to be sitting on the side of the road again. Going to replace them again with the right parts. Would like to know which one it is. The codes it is giving is p0320.

P0320 - No Crank Reference Signal to PCM

Possible Causes:

1. Crankshaft Sensor signal circuit open or grounded
2. Crankshaft Sensor VREF circuit open or grounded
3. Tone wheel or flex plate damaged or erratic CKP Sensor signals
4. Crankshaft Sensor is damaged or has failed
5. PCM has failed

Recommend checking the wiring going to the Crankshaft sensor before checking the Crankshaft sensor.

I have read post about the wires going to it. And i did have a wire that was messed up. That was the first thing i did. I fixed it and it is tied up out of the danger zone now lol. But then the code came back that is when i replaced the sensors.
