How To: Replace a Dodge Hemi Camshaft Position Sensor

If you are experiencing a hard start situation, engine stalling, rough idle and getting an OBDII engine trouble code of P0340 or 0340 camshaft position sensor circuit malfunction, you may have a bad camshaft sensor. This step by step video shows how I checked and cleared the engine trouble code and replaced the faulty engine sensor.

[@chrisswain4517]

Great step by step instructions. I changed mine out today in my 2004 Dodge Ram Hemi in about 35 minutes. Runs like new again!

[@drew856856]

Thankyou so much. You made my job easy. I have a 03 2500 5.7. i didn't have to take off the air box inlet. The hardest part was lining up the the hole with the screw to put ot back in. Thanks agian.

[@PersonalFitness3]

Thank you for making this video!! Had the SAME issues with my Dodge Ram Hemi. Was able to easily locate, remove and replace the Camshaft Position (CMP) Sensor. I used long-nose pliers to easily remove the sensor.

[@DanielScheerHowTo]

Thank You!

[@slughunter20]

Good video. Watched it twice and repeated your steps. Seems like it worked out fine. Thanks for the help.

[@criskucera4930]

I had this issue with my 2010 ram 5.7 hemi. I changed both cam and crank sensors but was still going into limp mode. I talked to 2 mechanics at 2 dodge dealers who wanted $135 to scan it and hope it came Bach with something. Then I talked to my local mechanic who told me the sensors needed to be resynced and offered to do it at no charge! Problem fixed it's been a week now with no issues

[@a1930ford]

How did you resync the sensors? Is there a video on such?

[@theSteve__]

What code were you getting?

[@michaelhakes5845]

Resync? Sounds like bs...

[@saulmorelos4556]

@@michaelhakes5845 well he did it for free so it doesn’t matter

[@GermanShepherdDaphne]

What were your symptoms?

[@a1930ford]

I believe that a PO340 and a PO344 code both would indicate this as a position sensor problem. My truck would quit after I shut it down, but then would not start no matter how much cranking you did with the battery. After a bit though it would finally fire up and run like a top. It did this twice last week and was frustrating as hell at the time. Looks like I will be doing this swap soon. Code readers sure are helpful to have. I have run into some parts places where they claim they can't legally clear a code. They can run a scan, but can't clear all the codes afterwards.

[@josephweiss7618]

also.. if you don't have a code reader, you can turn the key 3 times on-off (not fully, only to the accessory position and leaving it at the accessory position on the 3rd turn) and it will show the "P" code on the odometer, then show "done" when complete. You can't clear it, only see the code being thrown.

[@antcri730]

You mean the on position not accessory.

[@sergeant1hp]

Your the greatest, I installed the new sensor with no problems. 😅😊

[@davidmoran5971]

Thank you for sharing this instructive video. It is incredibly informative and it saved me over a thousand dollars for a dealer repair.

[@garyhooper1820]

Good video, had this issue with my 03 2500. Blind area ,but not a hard replacement. Like. The fact the engine would run not well but got me home. Til I fixed sensor. This has been a good truck.

[@BuckeyeMCS]

Great helpful video. Thank you. Don't you hate when someone works on your vehicle and either leaves stuff off or not connected. I'm curious on the broken valve spring, what were your symptoms? Having rough idle when warm on 2012 Jeep with the 5.7 with no check engine light.

[@joelunchboxx]

Broken valve spring usually gives misfire and low compression on compression check. But, usually you have to pull the valve cover and visually inspect to make sure. If it's broken, the valve cover is coming off anyway.

[@RV-ds5uf]

I have an 06 durango and the camshaft sensor keeps going bad. I’ve had to replace it 3 times with the duralast brand from autozone in less than 6 months. I finally installed an oem camshaft sensor that lasted longer than the duralast brand and I recently started having the same problem again. Im beginning to think i have a wiring issue. I’ve heard many mechanics say that Dodge is known to have electrical problems.

[@luisballes7514]

thankyou!! i was about to pay the dealership $500 because I tought it was the key that had to be reprogram. changed the sensor and it turned on with the first crank.

[@larrynance1269]

Was your can a crank no start

[@a1930ford]

On the corner of the valve cover there is a weird looking plug which holds the wiring harness into place there. I believe this is the area where you showed that there was a ground wire loose in your video. i do not with to snap off that plastic plug, but it has my wiring harness held so tight that I really can't get to that 10 mm bolt to remove the camshaft position sensor. How do those type of plugs work in being properly removed? Never mind, I went to a parts house and found a tool to remove that plug with. It will likely be a one use tool, but probably cheaper to get one on Ebay than at a local auto parts house. It is called Clip Removal Pliers. They worked great once I found exactly where to push them in. My trouble now is removal of that pigtail that connects to the camshaft position sensor. I have not been able to separate them, yet. It got dark so I will be finishing this up tomorrow.

[@a1930ford]

Is this piece actually just pressed into place? Will a flat blade screwdriver lift it out?

[@a1930ford]

Old mechanic told me that a flat blade screwdriver will likely break it, especially if the truck is older. Suggested to use Clip Removal Pliers from Advanced Auto or such. $23 bucks for an essential one use tool, but it worked like champ when I figured out where to insert it and how to avoid all the wiring in the way. (You can likely pick one up on Ebay much cheaper). I had to get over the engine from the front in order to put this tool onto that plug. Any rate, the wiring was so very tight and right in front of that camshaft position sensor that I could not get at the thing until I got that plug removed. It is actually a rubber piece slid over a metal stud on the valve cover. You could likely use a straight slot screwdriver, but my luck would be that it would break on me. I took out the 10 mm bolt okay, but separating that pig tail from the position sensor is a real frickin' challenge, for sure. Not sure just how that pigtail is supposed to be released, but it took super strength to do the job and separate the two. It got dark on me before I could insert the new position sensor, so I will have to continue tomorrow to get it all back together again. This video really did help me though. I did use the dielectric grease on the rubber seal and i hope I have no issues in reinserting it all and locking it down tomorrow. I am hoping that cures my stalling problem, as this happened earlier today and scared the poop out of me, as you lose all power steering and simply coast for a short distance. Cars parked all about the curb, so I had to try to make it around a turn, but the truck died completely and it took maybe 50 cranks before it turned back on as if nothing had happened. I caught every darn red light on the way home and sweated getting back before it did it again. This sensor had been throwing out a PO340 code. Hoping this cures the issue.

[@bro8759]

I am getting the long crank symptom on my 2008 Dodge Ram, but its not throwing any codes. Did you have the same symptom without any codes being generated?

[@jasenpalmer508]

[@jacobmartin1181]

I have a question. my 2009 Dodge Ram hemi drives great! But when I come to a stop, it drops in idle to 500rpm evenly every time (unless my a/c is on which is weird). BUT I can give it just a touch on the gas with out moving, and it corrects itself to 700.. it shifts great, runs strong and sounds healthy. It’s stalled a few times since I’ve owned it. I’ve replaced the MAP sensor and no luck. And cleaned the throttle body and no luck. Any suggestions? I might try to clean the throttle body a little more..

[@BrosOfArmz]

Been having the same problem I've changed about everything I could even had to replace the whole engine so I have no idea maybe it has to do with something in the transmission? Oh and the idle is supposed to be 500-900 rpm at idle on a stock 5.7 hemi.

[@GermanShepherdDaphne]

I have a 2009 5.7 hemi and been having issues where my park idle is at 500rpms and when I'm driving up the mountain truck stays at 2000rpms and won't go past 40mph unless I floor it. It shifts smooth on flat surface, but higher rpms like I'm not getting a connection or something. It's so strange. I read that this sensor can cause this issue that I'm having. I'm not stalling out though, and no rough idle.

[@saxoman1995]

I've had the same exact issue with my 2006 ram 1500 with a 5.7 hemi. Something that helped was changing the thermostat oddly enough. Before I changed my thermostat, the previous one was installed and correctly and my gauge would run somewhere halfway between the full spectrum of the full spectrum of the gauge. After I changed my thermostat, it would go up to about 1/4 of the full spectrum of the gauge and maintains that temperature constantly and The truck began idling around 600 RPM after the thermostat change.

[@krazycarlos7]

So i got the same code for my 11 dodge charger. Plus like you said i do have to step on the accelerator in ordered for the car to start. And also my traction controll light came on and woulnt go away. It came on when my check engin light came at the same time..

I’ll be going 50mph and rpms show it to be at 800rpms. Also sometimes has s problem accelerating. Could this be causing it?

Well i have a 6 cylinder 2013 3.6 and I'm trying to replace my camshaft censer but I can't find it..

[@a1930ford]

In looking up replacement position sensor for my '04 Dodge Ram 1500 Hemi, I found that at all the local parts stores, bar none, the aftermarket position sensors were rated as pure junk in most cases. The failed right out of the box or very quickly after installation and seemed to lack quality control for the part. Most of those rating them went back to the stock MoPar part and had no further issues once they replaced this part. I'd hate to install this and only find it to fail shortly afterwards, but that is how 99% or those who did this rated the aftermarket parts, no matter which of the three brands were used as a replacement. Thanks for the video as it looks like the typical old fart can actually do this and probably have the most difficulty in just finding a good step stool to use to get up there and work. Not sure if the DL grease is actually any better on those plastic contacts than contact spray would be. The stuff would work well as to the plastic body as you used it. Any rate, I enjoyed the video and was appreciative that you ended up with just enough lighting in the video to actually show the part location and all.

[@antcri730]

Did you just make that up? Most aftermarket parts are just as good and many times are better than oem. OEM parts are made as cheap as possible to increase profits.

[@knifeaddict1014]

[@crackerjax4330]

Not positive but I think that particular sensor gets a 1/4 turn counterclockwise to remove. That might have been why it wasn't cooperating. Then again, nothing ever does cooperate!

Couldn't figure out why he would want to introduce silicone into the cam lobe lubrication system. Thought i was the only one that thought that was weird. Don't think he knows what dielectric grease is for.

[@JOATJESSE]

The dielectric grease is for the connector, not the sensor itself. Lube it with engine oil. If it's stuck when removing then use a flat blade screwdriver and attempt to twist it around a little to break it loose and then wiggle it out once it spins some. Spin it a little clockwise and counterclockwise (in any order).

[@headpen102]

Mine did the same it turned out to be my spark plugs. Since you bought new spark plugs then that’s not your problem. You can also try changing your MAP sensor, or Camshaft Position Sensor, if it’s not those then honestly it could be your ECM. Or TCM, BUT do not change either right away because it will cost a lot

[@headpen102]

I have the same year and model, I changed my ECM, and TCM and it continued to stall. I changed my spark plugs and MAP sensor, it didn’t do it as often but it will randomly cut off and on while driving but it stopped stalling out completely.

[@JoseRodriguez-kt5km]

So Exxxtra did you check the wiring? They melt all the time arround the oil filter area

[@pauljohn6546]

So Exxxtra , it’s your fuel pump... Trust me.. People think that when your fuel pump goes out it won’t start, which is true, but in some cases the fuel pump WEAKENS causing to turn on and then cut off while you’re driving, they ignore the fact that sometimes the fuel pump weakens not going out in it’s entirely...
