What is a crankshaft position sensor?The crankshaft position sensor is located near the engine's crankshaft, and relays information about the crankshaft’s position as it rotates. Show
How does the crankshaft position sensor work?As the crankshaft spins, the position sensor magnetically reads its position. This information is constantly sent to the engine's computer for comparison with data from the camshaft position sensor. When the two signals reach the computer, they must match; otherwise, the computer will think there is a mechanical error in the engine and will adjust some settings in response. What are the symptoms related to a bad crankshaft position sensor?When the computer senses the engine is out of time, it will turn on the check engine light, and the engine may start and stall, or fail to start at all. If the engine runs, it will run poorly, and get bad fuel mileage. » LEARN MORE: Symptoms of a bad crankshaft position sensor Can I drive with a crankshaft position sensor problem?Driving a vehicle with a failed camshaft or crankshaft position sensor is usually impossible. If driving is possible, it is not recommended. If the sensor is functioning normally and reporting an error, the engine may be out of time or may have suffered a mechanical failure. How often do crankshaft position sensors need to be replaced?There's no set replacement interval for the crankshaft position sensor, and on many cars, the part will last the lifetime of the vehicle. It's not uncommon for it to fail, however, and the likelihood increases once you pass 100,000 miles. Joined

Have you tried screwing a self tapping screw into the remainder and use it as a handle for vise grips etc? If the oil pan gasket is a windage tray as on the 5.7, it could get picked up by the crank.

A Auto Parts Rep told me that I could knock the broken portion into the engine and it wouldn't harm it. Need a 2and opinion.

If the oil pan gasket is a windage tray as on the 5.7, it could get picked up by the crank. The way that the sensor broke....it's inside the block where as there's no way to pull it out. Meaning that the sensor's sealed from the internal side of the engine where as pulling it out would'nt be
possible. I've used vise grips to try pulling the sensor out after using my hand to do it and it did'nt work......which broken the sensor inside of the block. An Auto Advance Rep told me that I should be able to knock it into the engine block.....but I needed a 2nd opinion before doing so...since I'm considering extreme caution towards damaging the engine. He said that I was'nt the only one experiencing this problem and gave me a few options....such as drilling or chiseling it out which can't be
done because of the tight space the Jeep has in that area. I was thinking about heating it with a little bottle torch but considered the damage and danger that may take place. So As Of Now.....the only thing that I can do is to knock it into the engine block and pray that it'll chip off away from the block using a spike like construction nail that I've heated and bent into an "L" shape to fit in that spot to remove it unless someone has an better or more effective remedy.

My brother has effectively used a torch to super heat a broken part and remove it. I would drill into it if you can and attach a screw to use to try and pull it out if you can.
