Default Just purchased a 2007 dodge magnum sxt...

I just bought a new sxt and I love it. My MIL light has been solid lite though. I took it to autozone because they do the free engine diagnostic and they gave me the code p1004. Does anyone know what this code means? They couldnt find anything in their system or their code book. Please help...

i had this P1004 code on my 2006 sxt magnum too.

it was a short runner valve performance. the dealer replaced the intake manifold plenum. some other i know that have had this code just cleared it and it never came back. try clearing the code by pulling fuse #11 (located in the engine bay) for at least 15 seconds and see if it comes back.

My car (which is also a 2007 SXT) just threw the same code. Ive read on a Charger specific forum that it may be accompanied by loud ticking much like the sound of lifters under acceleration. My code reader said it was a one-time self-corrected issue so I cleared it. We'll see if it comes back. Anyone know how much a repair cost this is? Especially if not covered under warranty (My car is 40,000 mi)

my dealer said it was a $900 repair. i see the intake manifold online for less than $100 new. they said they replaced the upper plenum. that looks easy enough.

Another easy way to clear any check engine light is to disconnect the battery for a min then re-connect.

*dont own a Magnum, bored and forum hoping*

The code has not returned thus far--a $900 repair is not appealing. The intake plenums are about $400! Since its the upper most part of the engine one would hope its an easy DIY job.

Default Re: P1004 code for Dodge

Concerning the P1004 code... I own a 2007 Dodge Charger 3.5L. At my shop, after checking the light, Mitchell has a TSB out for that particular code. It is requiring to replace the intake plenum AND the actuator. Whether it is one or both, I am not sure at this time. Wasn't able to print out the TSB and our printers are down... computer problems. I also noticed that on my last tank of gas, my gas mileage dropped TREMENDOUSLY. I usually average 100 mi/quarter tank of gas, and on my last quarter, i usually get 50 to 75 miles before I have to fill up. Well, I got about about 225-250 miles on my last tank of gas before I had to fill up again. My driveability technician and I both figured to try a fuel system service to see exactly what that would do. The only reason for that is after removing the actuator, we could see alot of "oil" on the intake runners; similar to the oil that you would use for K&N filters, but quite dirtier. Needless to say, we did the fuel system service with a 3-part treatment from the Wynn's fuel service company, added Lucas fuel treatment (the quarts. 32 oz bottle. 3 oz per 10 gallons of gas, quite potent!) I have roughly a 40 mile round trip every day to and from work, and my fuel economy is right back where it was previous all these problems, about 100 miles on the trip with 3/4 of a tank of gas left. If this should happen to help anyone, please let me know. Both myself and my driveability technician are VERY curious as to see what these motors are capable of.

Thanks!

Well i am a bit late on this post but just got a used Stx 07 to and same problem same code but the car run's good and fuel economy is good to,
i just dump a bottle of lucas system cleaner in to 25 liters i have pull the fuse but after fews mile the engine light still coming back; so if i understand the problem the car engine is full of fuel and oil deposit, so pouring some fuel system cleaner should fix sooner or later ??

There are two TSB's, one to flash update the PCM and the other was to replace the short runner valve assy,it comes with the actuator.

Any updates on this? I have crappy gas mileage ( 13 MPG ) and P1004 code for months now, reset CEL only to have it come right back. Sprayed inside plenum with carb cleaner, no change, 2008 Magnum SXT 3.5. Any help please ?

you need a intake plenum and a PCM flash update. there is TSB on this one. spraying cleaner into the intake would not do anything, the problem the shaft inside the plenum that get seize up or breaks off.
regarding the fuel economy, the plenum should affect fuel economy THAT much.

Thanks Steak! Where is the best( cheapest) place to buy the plenum? How in depth is the installation? Have tools and engine rebuild experience. Thanks in advance. Eric

just google Dodge OEM parts, plenty of OEM dealers online, and pick the cheapest one. most of the time they have phone number for you to call, better to order thru phone and provide your 18 digit VIN number to make sure you get the right one. it will be few hundred dollars.

also, order a EGR tube gasket/seal that is between the EGR tube and the intake. They tend to rip when u take it out. and put a little bit of grease on installation.

regarding replacing it, all you really need is some general ratchet, extension, sockets, and wrench. probably ranger from 7mm - 15mm.

there is 2 bolts here to the passenger side
Click the image to open in full size.

like 8 small bolts on top of the intake manifold, and disconnect all your vacuum lines and connector to replace it.

the trick is, if you can't wiggle it out, you might have to lift up the bar #6, bolted down on both end with some 13 or 15 mm bolt.
Click the image to open in full size.

the other thing that might be in your way is the the ATF dipstick tube. you might have to SLIGHTLY bent it out of the way.

after you take it out, make sure you cover the Holes on top of the engine with towels or something, the last thing you want to do is drop something into the engine accidentally.

before you install it, look UNDER the new intake manifold, make sure all the Rubber ring seals at in place first.

good luck! it is fairly straight forward, should take you no longer than 1-2 hrs.

and you HAVE to do the software update on the PCM. call your dealership. If they want more than what you pay for, offer them $50, because there is a dealership farther away that would do it for this price which you do not want to drive to. At least that's the price our dealership charges.

Default thank you Steak!

Wow, I think you have exactly identified my problem!

But... I don't understand... why isn't this a recall?

I have a 2006 Magnum and the CEL is preventing me from passing smog.

I have had no other symptoms, other than CEL and don't understand how I will benefit from this repair, other than passing smog. My quote from a trusted mechanic was $2200!

Thank you!

How on earth does that repair cost $2200?
the intake manifold itself Listed price is $509, and repair is 2 hours top! including PCM update.
So much for trusted mechanic.

make sure you refer to TSB 18-003-07!!
part number for intake manifold should be 4591863AJ, but double check with your dealer and the TSB.

regarding recall, no manufacturer recalls things like failed part that doesn't jeopardize safety. It is what extended waranty is for. Sorry to tell you.

Default happy ending

good news, I took it to the dealership, and my car had a lifetime powertrain warranty. so the entire repair was covered - just paid the $100 deductible.

Just bought a 07 Magnum SXT and I love every bit of it. Had a problem passing Emissions at first, was getting the MIL error as well. Ended up bringing it back to Dodge and getting the Intake fixed. Total amount was 981.00. It cost me nothing, all this was paid by the used dealer I purchased it from.
