    I have a 2010 Tacoma V6 with a Magnuson super charger recently had my onboard ARB air compressor blew out two 40 amp fuses due to the cold weather here in the PNW after changing those I notice my front bumper lamps was not working I checked a few fuse pods and did not see a blown fuse assuming 30 amps plus fuses. I then started the engine and it stalled out never had that happen b4 so I repeated the same it ran with rough idle, took it for drive and discovered severe loss of power while driving up hill. Performed a OBD2 and discovered several codes on all four oxygen sensors both up stream and downstream and including the following
    P0102 Mass air flow-low, sensors Bank 1 sensors 1 & 2 , Bank 2 sensors 1 & 2 and a P0455 emission control system leak? I'm running Magnaflow's catalytic manifolds with flow master American thunder-cat back exhaust. I been to YouTube and found that performing a ECM reset solved the issue can I get some input from you guy's before into the shop again next week? I have attached a pdf of the all the codes hey my tacos dash lights up like a Christmas tree any way with all the aftermarket performance parts but has never had engine issues like these.

    Looks like the rear O2 sensor are missing voltage.
    And the fronts are drawing no current?

    I'm not at my computer at the moment.
    @Dm93 might be able to help you out faster.
    I'd need to look at some diagrams.

    Is the 15A A/F Heater fuse good?
    Do you have power to and out of the fuse?

    Might as well check the 20A EFI too.

    I'd suspect the EFI No2 fuse is blown, that would explain all the codes you have.

    Thanks for jumping in @Dm93 it was blown I checked the fuses that @TnShooter suggested as well with no blown fuses still experiencing same as mentioned then did a ECU reset and that solved most of the codes still have a P0031 bank 1 sensor 1 and P0051 bank 2 sensor 1, these should go away after putting 50-100 mi on the ECU.
