    P0100 maf sensor?

    P0110 iat sensor? If so how do I know if it’s a separate part or built into the maf on my 3.4 Automatic?

    P1135 is this the 02 sensor next to the engine or the rear of the exhaust?

    P0330 Uhggg dreaded knock sensor?

    I will say that I have been on a Tacoma forum on Facebook for a while now and people on there only want to put you down. Needless to say I’m removing myself from the Facebook group. This group is phenomenal!!!
    Thank you for any advice, you guys are awesome!

    just cus it says O2 sensor doesnt always mean its the sensor, something before it might be triggering it, or by resetting the battery it will go away and hopefully doesnt come back. How is she running? Get a live data obd2

    I’d address the 100 and 110 before I looked at anything else.
    The IAT is built into the MAF. If you have a scanner, see what IAT reads. On a cold engine, engine Off, the temp should read at/close to outside air temperature. (This is a quick and easy go to test)

    @Oldman808 , I purchased that as well. Should be here soon. Thank you!

    @YotaGangYotaGang , runs good on flat but not so great on steep uphill 4 lane or 2 lane roads the rpm stays low until it tops the hill, then it takes the gas. I’ll try to get a live reading and post it. I don’t know much about the OBD things except to get a code. Thank you!

    @TnShooter , I have a new Densa maf coming. Thank you!

    Guys I also ordered new dual end platinum Denso plug as I think the ones in it are single prong.

    Just google obd2 live read app near me and you can purchase one and you’ll download an app, all you do is plug it in and screenshot and post on here and we’ll tell you whats off. Start off easy. Has it been maintained? If not start simple clean the maf, reflace air filter, change plugs, do a conpression test and a leak down test

    Update: The new Denso 02 sensor and plugs arrived yesterday! I was able to get them installed last night and all codes other than the P0330 was cleared...
