p1391 dodge ram

p1391 informative video for the different crankshaft position sensor

[@WetNets75]

Wish I had found this yesterday before I installed my aftermarket sensor. I am not taking it out to satisfy my curiosity, especially with heat index hovering at 109. 🤣 Unfortunately I may have to, because I still have a no start. 🤨😒🧐 Appreciate the video, as I couldn't figure out why the store didn't have a cam sensor, nor could they. 🤔 Google and forums were just as useless. Thank you!

[@tomjohnson3773]

Fought my crank cam intermittent problem. This great video. My original sensor showed higher magnetic field on a gauss gage app I downloaded. Both aftermarket sensors had weak readings so I put old sensor back in and it runs perfect now. Thanks for this video.

[@christianschool2082]

Awesome video very informative and a relief to hear similar symptoms

I also have the error with my 1998 5.2 liter magnum Dodge Ram, would the one from mopar work because I've already exchanged so many, it was in 4 workshops and nobody found the error

Great learning video, thanks!

You're a Genius, Thanks for helping me out!

Had the same magnetization issue with a Walker branded one I picked up from RockAuto. Swapped it and got one that would magnetize. Definitely take your original to the store when you purchase or atleast check magnetization before installing the new one.

[@2001BornAgain]

I got one at Advance Auto and it wasn't magnetized. So I had to get the OEM and that thing was $129! But my truck started so I guess it was worth it.

God this will help so damn Much

[@kennethrini2932]

Thanks for the great explainations

[@XMindXBodyXSoulX]

I had the same issue with a Jeep Liberty a while back. I kept getting cam and crank sensor codes after I replaced them from the parts stores. Everyone told me it was a timing chain. A forum suggested OEM sensors so I tried it and the issues went away.

I got a 94 dodge ram I have put a cam senior rotter button and Distributor cap plugs and wire I have not chande the crank senior the truck will not fire the plugs or coil would the crank senior stop it from firing

[@beardedcapricorn8458]

When I installed my crankshaft from O’Reilly’s and sounded like my fly wheel was out of sync thank you I’m hoping the Mopar one will help me

[@Rodneyzoom]

Bro good luck I pretty much overhaul my top end but I haveny touched the bottom at 400k the truck runs amazing wish Facebook let me post a pic

[@colbycolwell7662]

will those code cause low oil pressure?

[@blackshirt4ever02]

Did that work for you? I got the p1391 code after doing my head gaskets too.

[@Rodneyzoom]

No I didn't it end up being a loose rocker which cause the intake valve not to open . So I will say check your push rods

[@2001BornAgain]

@@Rodneyzoom I just changed mine out and I hear something in my #1 cylinder. I wonder if it's a loose rocker arm. Sounds like a knock, but not a deep knock like a rod. Was it an easy fix? I've been on this truck for a long time.

[@Rodneyzoom]

That's how mines sounded put your hand on the valve covers while running you should feel any knocking if it's top end

​@@marcelblumberg4353yes it will

Well done

[@JuanGutierrez-hg1jc]

thanks man that helps alot.

[@justinfincher2385]

Dude. I just changed mine about an hour ago and I was legit checking to see if there was magnetism. I bought it from O’Reilly’s and there wasn’t any magnetism. So I tried the one I just took off. No magnetism. I thought, okay, maybe they’re not supposed to be magnetic. Well sure as Jesus wore sandals, even though it runs better, it’ll still randomly backfire and lose power. I’ve replaced any and all sensors, it absolutely HAS to be this sensor. Because temporarily after changing it I’ll have power again, then it goes back to its old ways.

[@Rodneyzoom]

sorry for late response have you fixed your truck and what was the problem

[@talesfromthebutchside5613]

I gotta pull mine off my '95 ram. Got any advice that doesn't include removing the engine or pulling the cab off lol?!

[@Rodneyzoom]

Remove valve cover to get clearance outside of that you could go from underneath if you can see through the exhaust

[@talesfromthebutchside5613]

@@Rodneyzoom thanks! I'll give it a shot!

[@BST-lm4po]

@@talesfromthebutchside5613 Did you find any shortcuts or tips to share? I've got to change mine on a 95 Ram. It looks like a tough spot!

i cant find my cps on my 2000 dodge ram 1500 4x4 v8 5.2 sport??

[@1stopslabshop]

Maaaan I just put a aftermarket 1 in mines and now my truck want stay running ima swap it out with a oem 1 this weekend and hopefully that fixes the problem

[@Rodneyzoom]

Ok let me know update the dodge place stated that they discontinued parts for my 02 ram in 2010 and I bought the last crank sensor in southern east coast supposedly

[@1stopslabshop]

@@Rodneyzoom yea I seen some other brands online with the magnet stripes on the front I’m going to try those first

[@Rodneyzoom]

Good luck after market sensor the truck seem not to like it

[@richardcerruti8295]

im pulling the 01391 code i change the whole dist. with can sensor also change the crank sensor when it came out it had a ball bearing attached to it.where did it come from? it still wont run above an idle any thing higher it misses bad.

[@Rodneyzoom]

that's probably one of the magnets off of the torque converter/flywheel. The flywheel is welded to torque converter and on the motor side of flywheel there magnets welded Ive seen some glued on some aftermarkets. so 2 choices either replace torque converter or if you have the tools and skills you find the broken weld area on flywheel and spot weld or jb weld magnet(ball bearing) back in place

[@beardedcapricorn8458]

What made you think to try Mopar what went wrong

[@Rodneyzoom]

When I got the new sensor it thru a code for crank shaft and never ran once I put the original one back in no code so I figured the aftermarket was crap

[@richardcerruti8295]

its on a 1996 ram 1500

[@Rodneyzoom]

Yes it is 5.2 and 5.9s
