BETTER GAS MILEAGE IN A JEEP??? - P0335

Rough idle? Lower MPG than you used to get? Even WITHOUT a check engine light, this will make your jeep run like new. It’s cheap and if it takes you 10 minutes it’s only because you took the time to drink a cup of coffee!

Mopar Crank Position Sensor for a 2015 Jeep. This will work in some others but be sure to check for your year and be sure it’s MOPAR!!!

Changed my crank sensor last week before seeing this video.
I’ve a ‘96 XJ. Wow what a difference for sure. 253K miles and still strong as ever

[da.vo.]

Hey thanks for this vid - took a flyer on it and I perceive a smoother acceleration and so far about a 10-15% increase in fuel economy! Pretty happy with that, thanks for the tip

[brainards]

You are totally right! I changed out the CPS and jeep runs much better!

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 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.

Bro your balance bead video was 110% accurate and a complete game changer on a 35s thank you for the content

Had the same issue recently on my 2016 with only 32K on it. Same thing, no code thought it might be the throttle body or peddle assembly, but nope crank position sensor. Cheap and easy fix and makes such a difference.

GREAT VIDEO! I had this same issue in my 2012 with only 76k and now I run like new....

[mr.beepers]

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 getting excited about that prospect!!

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.)

[grenou]

Thanks for this video! I've been stressing out and scratching my head as to why my Jeep was performing exactly as you described. And yes, it is a higher mileage 2012 JKU - 250K+ Km on it. Sourcing a new CPS, right now...!

[anibalbabilonia]

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!

[garrettbrown]

Wow, what a difference once I swapped out the sensor, thank you! I wonder if changing out the camshaft position sensor would have similar benefits as well?

[zackbrown]

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

[nleippe]

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.

[marioalvarez]

Mine is doing the same thing and I have a little more miles than you do on my 2015 jku. I am going to change it out!!

[mattpittman]

Just happened to me today, no dealers had it so had to buy one from O'Reilly's (lifetime warranty) and ordered the mopar sensor on amazon. was on the freeway and when i would accelerate it would break up a lot and felt like it wasn't getting fuel. got off the freeway and it died at the stoplight but started back up but threw a p0335, quick check online lead me to crank position sensor. Thought i would be able to at least make it home but it started getting worse in freeway traffic so a target parking lot switch over and i was back up and running. 2016 jkur 103k miles gonna order another one and two cam sensors since the passenger side cam sensor left me stranded last year so i'm figuring the drivers side will go out sooner or later.

Good Video, very detailed. Nice Job. Mines a 3.8 but I wanted to show some appreciate for your Channel (Subscribed)

[America_took_my_zebra_stripes]

I put sea foam in my 2009 jku.3.8L and went from 232 per full tank to 268-275 extra miles per full tank till reserve light illuminates.. and once in a blue moon to 296 miles per full tank

[NaikeishaCampbell]

I just changed mine out yesterday so hopefully it doesn’t stall out on me again 😅that is super scary!
