Review on 🔧 Enhanced Performance Crankshaft Sensor by Standard Motor Products, Model PC684 by Nate Nelson

Here is my experience with accidental engine shutdown: 2012 Jeep Patriot Latitude 2.4L 4x4 with manual transmission. I started having random shutdowns while driving. This usually happened when accelerating to city speed, usually in 3rd gear. The instrument panel continued to burn, the radio continued to work, but the revs dropped to zero. The first few times it started again while driving, after that it took a few minutes to cool down before it would start again. The check engine light came on the first time and stayed on for several days before going out. After the first few shutdowns, it didn't stay on for more than a key cycle. He did this about ten times over the course of about two weeks. I took it to the parts store to have it scanned and it showed about ten codes, about 5-6 different ones. One of the recurring ones I noticed was a crankshaft position sensor A circuit malfunction (P0335). Got one of these, plugged it in and three weeks later it wasn't even working. Installation turned out to be easier than I expected, but I consider myself quite adept at handling cars. Installed and assembled in about an hour. I did this by disconnecting and removing the battery, removing the airbox (and two large electrical plugs from it), removing the exhaust manifold heat shield (after the car has had enough time to cool after driving) and then removing the smaller vertical straightener a heat shield held in place by two bolts and a nut on the rear of the engine (driver's side) to position the crankshaft position sensor underneath. There is a wiring harness that goes to the crankshaft position sensor - I believe it also connects to the camshaft position sensor which is much more visible and accessible. The crankshaft sensor and the heat shield covering it are removable with 10mm and 13mm sockets. I don't remember what I used or where, but if you're doing this job you should already have sets of 1/4" and 3/8" metric sockets with extensions and at least one swivel, which you may or may not have don't need. . These screws are awkwardly located and not easy to see. You'll have much better luck finding your way to the bolts with your fingertips. Once you've removed the smaller heat shield, the sensor can simply be unplugged and removed using a 10mm socket. I've seen many mentions on the forums of retraining procedures that involved accelerating to 70 mph and then free running to 40 mph. and then repeat the process. I can't say if that's really an important step, but actually I didn't notice any difference in the car's performance by skipping it. TL; DR, the item works well, I am satisfied. The installation was moderate.
