Limp Mode, codes, 2013 Tundra issues

CEL, 4LO blinking and TRAC off lights all on. Throwing codes: P0102, P0037, P0057, P1613, P1614, P0037, P0057. Truck turns over and immediately shuts off. Could I have a secondary AIP issue? MAF? Battery? Please help point me in the right direction. 5.7L V8 2013

 

That's a whole lot of issues.. probably a rodent got you. I'd start checking wiring before you start loading up the parts cannon.

 

Wires to both O2 sensors look fine, I don’t think there’s many rodents in my area either

I guess I’ll start with replacing the downstream O2 sensors, I didn’t have any blown fuses though.

 

I wouldnt start throwing parts at it just yet. Have you checked the battery voltage? Have you tried disconnecting the battery for a few minutes then reconnecting? Look all around under the hood at connectors and make sure it all looks good.

 

Also,I am no mechanic so I could be giving bad advice, but usually I am able to fix my vehicles. It looks like all your trouble codes are related because they are all on the 5 volt reference circuit. Watch this video about the secondary air pump 5 volt reference and how it shorted out the 5 volt circuit and caused the truck not to run.

The first thing I did was tried resetting the ECU by disconnecting the battery, no dice. Threw in a new battery as well as that was my first guess as the other was on its way out. Still nothing. Initial inspection shows all wire harnesses looking to be in fine condition. Haven’t started going deeper though. I’ll look more into the 5V reference circuit.. interesting for sure

 

What’s strange is that I have a crank, start, but immediate shut off situation.

 

Any progress?

 

Between work and life, it's taken a bit of time to figure this out. I located a small bit of wire on the Bank 2 sensor 2 O2 that had the insulation stripped away and a bit off corrosion. I replaced that first. For some reason, this allowed me to turn the truck on and it stayed running in limp mode, but the codes wouldn't clear. After inspecting everything else, testing AIP continuity, they seemed fine, my only concern was the secondary air drivers. I reached out to Hewitt (company that supplies AIP bypass kit), and they weren't convinced that the bypass kit would be the solution. I couldn't understand why the 10AMP EFI NO 2 fuse wasn't blowing, and decided to try and inspect as much of the wiring as possible. This led me to the fuse box. As it turns out, at some point (most likely with pervious owner), a rodent had made a home under the main fuse panel. It had chewed on a few wires, causing corrosion on the tiny 24 gauge red lead wire from the EFI 2 fuse. One day, it just decided to give out, causing mayhem to my circuit and throwing all my codes. Damn needle in a hay stack.

 

The tuck is no longer in limp mode, but there are 4 permanent codes being thrown by the computer. I was hoping that they'd get resolved by driving around a bit, but they still haven't gone out yet. I'm still showing a Bank 2 Sensor 2 stored code, that comes back after a while. I'll try changing that O2 sensor as well in hopes this clears my codes.
