That’s awesome!

Thanks for the video on crank position sensors and lack of engine codes. Excellent. Just FYII: In electromagnetism, a dielectric (or dielectric medium) is an electrical insulator that can be polarised by an applied electric field. When a dielectric material is placed in an electric field, electric charges do not flow through the material as they do in an electrical conductor, because they have no loosely bound, or free, electrons that may drift through the material.... Dielectric grease will protect a connection. It seems to me, I could be wrong, but first make the connection, then apply the grease over top and around the connection. Any E field from the connection, wiring, etc, will then be sort of neutralized by the polarization of the grease molecules and corrosion will not be promoted. At least that is my guess. A lot of folks say dielectric grease is conductive. Get an ohm meter and stick the leads in some of the grease. See what you measure. (I have not done this, but have on regular petroleum grease.... high resistance measured there, I don't recall the reading atm.)

Glad it helped! I know. I completed screwed up on saying what it was. It’s not something I use often…thanks for the catch!

I was on the freeway tonight and threw my JKUR down into 5th gear and hit the gas only for it to fall in its face. Did it the whole way home after that with any more than 1/2 throttle. My first thought was “130k miles... it’s gotta be the the crank sensor.” I know what I’ll be doing for 15 minutes tomorrow. Best wishes!

I just ordered that part straight from Mopar for mine. I took the jeep to the dealer and explained the issues I was experiencing, and they can’t seem to find anything wrong with it! It’s not showing any codes on the dashboard or anything! I also told them about the smell of gasoline too! But they said they did a diagnostic and nothing shows! Thanks for the video! Hopefully this is the problem with mine!

Got a 09 jeep wrangler 3.8 going to try this tomorrow get 11mpg highway no Throttle response. Have to shift from 6th to 2nd to pull hills hope it works

I cannot tell you how happy I am to have come across this video. I did not have all of the symptoms that you listed but I have been scratching my head about the erratic gas mileage and weird throttle response at low RPM and low speed that I've been getting. Just for the heck of it since it was so cheap and easy to do I changed my crankshaft position sensor just now and I'm out test driving it and getting four more miles per gallon. I am not exaggerating. The Jeep has 115,000 mi and I have done many things recently to try to fix this. Spark plugs did not help. Air filter no among many other little things. I'm not even sure how the crankshaft position sensor would even affect the symptoms that I was having. I do understand for the most part but the sensor does but never would have guessed it would have contributed so much to this fix I could go on and on. The thing just feels different in a good way. I wish there was some way I could force any JK owner to do this fix for how cheap it is and I can almost guarantee you'll feel a difference.

I am guessing that this sensor's proximity to the catalytic converter could be the problem. Even though it is shielded it is very close. I know that my Jeep spent a good part of last summer in an overheated condition, due to my wife! And I'm wondering if this is what caused the problem.

Thanks for the support and I’m glad it helped you! It’s a very common problem. It’s amazing to me that these Jeeps being as “smart” as they are won’t throw a code for this until after it literally stalls on you number times. The heat definitey isn’t helping them. But this sensor also uses crankshaft position to help control the fuel system. So it all makes sense that you are seeing a better increase in mileage! Awesome. Thanks again for the support!

same issue here, no check engine light.. gonna try this tomorrow...

I'm far from a mechanic, but when my #2 head was on recall, I swapped out both heads and all the cams, lifters, rockers and the mileage dropped 2 MPG. After thinking about it, even before I watched this video, I decided to replace the MAP sensor, Air charge sensor and the crank position sensor when the parts come in!! I hope it's the answer to my problems!! Thanks for the video......I'm getting excited about that prospect!!

FYI dielectric grease does not conduct--it's a very strong electrical insulator. However it is purposefully highly viscous so is easily displaced by tight-fitting components--eg electrical connectors when pressed or slid together essentially mechanically wipe themselves clean of the grease in the process resulting in a strong contact, which is immediately surrounded and still coated by the grease protecting it from moisture.

Thank you for this info I always thought it was conductive. I found this and it all makes sense now. "Dielectric grease is actually an insulating material that isn’t capable of conducting electricity. It is a silicone-based grease that is nonconductive and its main purpose is to prevent corrosion on electrical connectors and creating a barrier between the metal and the elements."

You sound just like me bro. I used to believe that dielectric grease could conduct electricity, but it can’t. It’s non-conductive. It only helps to keep corrosion and dirt etc out. The reason it is non-conductive, is because you can’t have a situation where you are losing/bleeding current, through the grease and out.

I can’t speak for the 3.8. I know that all modern day engines have a crank position sensor. So it probably couldn’t hurt to try and change it, they aren’t expensive. Some engines though have it located in a spot that requires a lot of effort and time to change it. If the 3.8 is one of those engines the. It might be worth waiting until you have an issue. But take a look and see where it is. If it’s easy to swap I would.
