Where DO I FIND the crankshaft position sensor on a 1999 Chevy S10 4-cylinder?

No need to jack up the vehicle with this job. I slid right under with a flashlight and was able to do it in 10 minutes on the ground. The sensor is below the coil pack, but further down. It is actually below the oil filter and directly next to the oil pressure switch. being a 10 dollar part, it's funny how shop labor is .75 hours and average price for part and install in my area is 85 bucks. I did this for 20 bucks, and 10 minutes. Easy fix for someone who knows their way around a socket wrench. Tip: 1/4" drive ratchet and 10mm socket will work much easier in this application. You will probably have to kinda pry the old sensor out with a flathead screwdriver and you will loose just a tiny tiny bit of oil when it comes out, so move your face when you pull out the old sensor.
