Raaammmathorn, I know this is an older post but I just wanted to touch base to see if you ever found a resolution to this issue? I have the same exact situation that you have with my 2013 Ram 2500 5.7 that I bought used in 2016. Within the first 6 months of owning the truck I would start getting the P1004 CEL mostly after hard acceleration on the highway that would then turn off by itself after a few days of normal driving. I did see the TSB's that were mentioned in other posts but those only applied to 2009 vehicles which I figured was because after the 2009 model they realized the SRV wire harness was too short so for future models they ran a longer wiring harness when they were being built. I replaced my SRV and completely cleaned out my intake manifold while I had it out but only a month or so later the code came back. The next fix was going to be replacing either the intake manifold or PCM but I didn't see how a new manifold would be any different than me completely cleaning out my existing manifold and installing a new SRV in it and the PCM was going to be expensive and didn't want to just throw expensive parts at the problem that may not fix it so I didn't do that. Basically since 2018 I have just been leaving it as is and when the CEL comes on for that issue I just drive it without pushing the throttle too much at once for a few days and it will just go away. I have had to plan my vehicle inspections to try and schedule them the day after the light turns itself off and basically don't drive my truck until the appointment so the light won't turn on which is a pain. It has actually gotten to the point that if i'm on the highway it will sometimes happen even if I don't do any hard acceleration and I can pretty much feel by the way the truck ever so slightly will skip/shake for a couple seconds and I feel like I don't have much power that I can look over at my wife in the passenger seat and say the check engine light is about to come on and sure enough a few seconds later I hear that familiar ding and the light illuminates.
If you have resolved this issue with your truck please let me know what finally fixed the issue for you and maybe I can see if that works for me as well. I appreciate it, Thanks
Hey! Did you ever get this sorted? I just bought a 2013 and it threw P000B and P1004 on the way home from the very small selling dealer over 4 hours away. I drove it for a week and the light went off while waiting to get it into service. I got it to the dealer yesterday, they did the fix for the P000B (remove intake manifold and replace the solenoid). But they didn't look at the SRV since they said they recommend doing one thing at a time, this solenoid might fix both code issues.
On the way home going steady speed an highway, I get the dreaded ding again. Ran the code and its now just the P1004, as apparently the solenoid code is now a thing of the past thankfully.
I had gotten check engine light under hard acceleration for the first time on the way home from the truck purchase. This time I got it just driving steady 70 MPH. Same symptoms as yours. Did you end up getting this resolved somehow?
I bought this based on the 2009 TSB for this issue, but am now pissed because the dealer already had the intake off and now I would have to pay that labor again to install it... :

Supposedly this motor and harness was the fix for this SRV issue, although I assumed it was 2009+ not just specifically 2009? Hoping to hear your solution if you found one.
Thanks!
