I was replacing my alternator and broke the CPS. When trying to pull the CPS out it broke even more and was flush with the hole. After reading some forums online i found a way that was working for most people. This included drilling a small hole and inserting a fine thread screw which you can then pull on to pull the CPS out. In doing this I accidently pushed the sensor all the way into the engine. I can still see it when looking down the hole but it is now offset from the hole and i cannot move it anymore. Looking at the underside of the car, it looks like i can remove the oil pan and then the broken part of the sensor. Am i correct or is the a better way to remove the piece or is it now impossible to fix?
