power amp and check engine light

2010 Tundra reg cab 2wd 4.6 l
owned since 2020
156,000 miles.
Put a Kenwood DNX 6972 HU in as soon as I bought it.
No problems at all
This past Sunday put in a subwoofer to fill out the bass.
ran 1/0 copper wire from battery +, 16 ft run, could make shorter but waiting to see where exactly I want all this to reside.
cleaned up both battery terminals with cleaner and coated with terminal protectant
1/0 ground to the chassis right by the driver seat in the door chase.
that bracket down to bare paint, the ground cable is 18 inches long
all connections through distribution blocks bought on Crutchfield
8 gauge to an Alpine Vpower mono 250w amp
JL 4 ohm enclosed sub
fuse blocks where needed


sounds awesome,
Drove 1 and 1/2 hours to work and almost all the way back at night , no problems

few miles from home, check engine light comes on. Truck running fine.
check codes p2714 and P2445
tried to erase codes but cant both labeled permanent.

question:
-coincidence and I really those 2 issues?
or
-so sort of interference ?

 

P2714 TOYOTA Code Pressure Control Solenoid 'D' Performance/Stuck Off (autocodes.com)

P2445 TOYOTA Code Secondary Air Injection System Pump Stuck Off Bank 1 (With Video) (autocodes.com)

I'm no mechanic, but I can't think of any reason your amp install would be the problem.
Could be a coincidence.

Does the truck shift any differently?

Hopefully your air pump doesn't go out.
Mine disintegrated in my 2005 at 95K miles.

AND welcome to your 1st post on the forum after 2 years...

 

THanks, yes I am a lurker. I mostly find the answers I am looking by reading previous threads.
I havent found this one so I thought I would give posting a try.
Im no mechanic either but do dabble with the audio in my vehicles.
I did ride all the way home with it pretty close to be maxed out and it did sound awesome. SO clean.
At first I was thinking a voltage drop because maybe my alternator cant handle it. But I got a second hand answer from the husband of a friend who thought my 150 amp alternator should be just fine.
I got those same descriptions and when you dive deep into causes it says that the return aberant voltage triggers the code.
Truck runs perfect, no shifting troubles.
If either of those is dying , I definitely want to fix it before I take off on a long trip
thanks for your input.

 

Hewitt bypass and keep on rockin

 

Will that just by pass the possible air pump trouble?
Dont I need that air pump to function as intended?

 

yes bypasses the saip system if it doesn't operate it can't fail
If one of the ai valves gets stuck open the truck will go into limp mode

 

If it's the EPA asking then yaesh, yinz need that pump.

 

That sounds like a good reason to get it
Im new to this and learning all about it
thanks!

Lastly @hagrid is 100% correct,

It is illegal to remove, dismantle, or otherwise cause to be inoperative any pollution control device required by federal, state, or local emissions law.

 

What'd you end up doing for the P2714 code?
