    I have a 2007 toyota tundra v8 sr5.

    im getting codes po113 and p0102. I’ve
    Changed the sensor and still same thing. After metering the wires, I’m getting

    12v power
    5 v signal wire
    2 wires are for the IAT built into it

    the ground I’m getting 1-2.5 ohms with probe to wire harness and negative probe in battery at terminal post

    With key on I’m getting 60ohms.

    many ideas on where to start?

    Is the air filter clean, is it sat in it's box properly, does the air box seal properly?

    EDit: Basically what the above poster beat me to!

    No mods, factory filter clean…. Just bought truck. The only mods I noticed was upgraded led head lights and radio. I can start the truck and it runs for 30
    Secs and sometimes the belts squeal…. Then it stalls out. I had someone tell me the timing belt is out of time. That is the reason for the low ohms on the mass air flow sensor. Wouldn’t that still be at close to negative ohms at start up? I’m getting 60 ohms with the key on acc…. Then with key out I’m getting 1-2.5 ohms..

    Ya know…

    much appreciated all the comments and help…

    I also forgot to mention that the first 4 plugs was misfiring when I first bought. All front front 4 plugs. I changed the coils and plugs… and maf sensor at that time. The plugs was very wet, but didn’t look caked or burnt?

    Have you replaced the valve cover gaskets? I don't think we're victims of the cam tower leak, but you may be getting oil in the chamber causing a misfire on all cylinders. May have a heavy leak on 1 and 8 which are interfering with spark. I'm no expert, but just an assumption since you mentioned coil packs were wet.

    Have you solved your issue? I am experiencing similar issues. However I have been thinking my valve cover gasket may be the culprit for my air leak. Also truck refuses to stay running unless I remove my gas cap, then It will idle, roughly though. If I put it in gear it will stall when lightly on the gas, tells me there is an air leak past mass air sensor since that reads 0.01. Frustrated as It all started with a crank no start, and no codes so replaced fuel pump, (same crank no start issue),replaced pvc valve, and maf sensor, aswell as fuel pressure regulator. Have been away from home for a couple weeks since truck is on a dirt road one county over and would like to get this fixed and back home for Christmas. Any help / advise is greatly welcome and appreciated!!
    Truck has 217,562 miles. also experiencing multiple cylinder misfires now that it’s idling with gas cap off, weird to me it runs with it off better than on… and the misfires for the cylinders is new, was running beautifully with no timing issues.
