Codes P0455 And P0449


Recommended Posts

Posted

I'm showing both these codes now on my 06 5.3 Crew Cab with 40,000 miles. previously I have seen just the P0455 (Tighten Fuel cap) code but it's not been the fuel cap. I've suspected the solenoid. With the P0449, does that for sure indicate a bad solenoid?

 

Replacement part number and source would be great if anyone has done this to an 06 5.3

Do a search on the P0449 code & you should find all the information that you need to fix your truck. To answer your question, yes it's the solenoid as I've had to get the same solenoid replaced. Unfortunately I found this site about a month too late & paid entirely too much at the dealership to repair my truck. Good luck from your neighbor in Georgia.

I used AC Delco part # 214-2149 from Rockauto.com on my '06 Silverado E/C....a few feet of 5/8 heater hose, 2 clamps.....15 minutes under the truck, and it's done. The one thing I would do different myself is to use something that is not as thick walled as the heater hose....too bulky in my opinion....also, took 3 driving cycles for the CEL to go out.

Perfect, thank you kind sir. I knew someone had the information that I was thinking about handy. :)

Thanks for the help and the video link. One more question. One response calls out AC Delco part 214-2149 which i think is the same as GM 25932571. Amazon says this one does NOT fit my truck. I have also seen a reference to AC Delco part 214-2082 which i think is the same as GM 19152349. This one is more expensive and it looks as if this one has the filter box with it. It also has 2 hose outlets where as the 2149 only has one.

 

What determines which one I should use? I'll get under my truck tonight and have a look to at least see if my solenoid has one or two hose outlets. I guess if it's one than the 2149 is it.

 

Thanks,

Thanks for all the great help and info. I'm going to get under there this weekend and verify what I've got and which setup I need to buy. maybe I cana get rid of these codes once and for all.

MIKE..............My 07 gmt-900 was throwing the 0449 code.

I just took the evap. sol. off and cleaned the crud out of the

vent hole in the solenoid and cleared the code.

 

If you read the link I posted GMs fix for this was to relocate the

evap. solenoid. The link explains BOTH fixes.

 

You can either replace the unit in its factory location with the OE

part or do the relocation procedure repair.

I guess it comes down to $ as the relocation and adding filter box is the more extensive option. I don't drive in dusty conditions so i may opt for OEM replace. I did take the solenoid off once and try to clean but codes came back. Thanks, Mike

OK, bought the 25932571 solenoid from local dealer $31 and some 5/8" heater hose and clamps and replaced old one. Disconnected battery to see if that cleared codes but not yet. I'll drive it a week and if they don't clear on their own I guess I'll go to AutoZone and see if they can clear for me. Hope replacing this fixes this problem once and for all. It did cure me of trying to squeeze a little extra gas in. Now when pump clicks that's it!

 

Thanks for all the help.

I had the same codes about 8 months ago, before I replaced that solenoid I was told to run sea foam through and it somehow fixed the problem and its never came back yet.

MIL Light went out this AM on the way to the gym! Maybe I'm good to go. Thanks again for all the help.

I know this is an old thread, but can you share the video link?

 

My "new" 2004 is giving that same code (along with a few others! damn used trucks!).

 

thanks

    • This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.  
    • 2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.  
    • Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
    • Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
