I have a 2012 nissan pathfinder with about 112000 miles on it. Last week it randomly started dieing while I was driving on a trip. I limped it to autozone and thought it was electrical at first because the battery was old and the positive terminal was badly corroded and slightly broken, so I bought a new battery and replaced the leads. 30 mins later it died again and wouldn't start. I thought it was the fuel pump because it would turn over but wouldn't start. Had it towed home, and could here the pump engaging and vehicle would start again, so I figured maybe it's still the pump or the fuel filter. I checked pressure at the fuel rail and got 50 psi which is about the operating pressure of my vehicle. I went and bought an obd11 reader and even though the check engine light wasn't on, it was throwing up a P0335 crankshaft position indicator fault. So I changed out the sensor, but im still seeing a fault. I checked voltage and was getting voltage, but im at a loss for where to go next. I read about doing a crankshaft position indicator relearn, and I really hope that's it. Is there a way to do that on my own with a simple reader? I'd appreciate whatever help I can get.
