    Hey guys...

    I just hooked up a scan gauge to my truck and got a few codes that I need help with...

    I know I need a new air/fuel sensor so the p1135 is no surprise.
    (could this be causing the other codes)

    p0110 IAT Sensor Circuit (can't find anything on this one)

    and

    p0100 MAF Circuit Malfunction
    found this-
    Possible Causes:


    MAF Sensor circuit open or shorted
    Intake air leaks (unmetered air after MAF Sensor)
    Defective MAF Sensor
    Electronic Control Module (ECM)/Powertrian Control Module (PCM) concern

    Diagnostic Help:


    Monitor MAF Sensor voltage reading while increasing engine RPM. The MAF Sensor value should increase in proportion to engine speed. If not, first check for air leaks at intake tube, manifold and all vacuum lines. Then test the MAF Sensor circuits for opens and shorts. See our article Automotive Circuit Testing 101, if you need more assistance with this. If concern is determined to be intermittent, wiggle test connectors and wiring to attempt to duplicate concern. You may also use the "Get Help" link if you need specifications or have any other related questions. Remember to refer to an appropriate manual for specific instruction.




    Any help would be greatly appreciated or sharing of past experiences.

    hmm, looks like everything is pretty much interrelated to me. cant really help you more specifically though. i'd try replacing the AF sensor if you know its bad and then see if you still trip other trouble codes. i think it may be the root to all the problems but cant say for sure.

    +1- Fixing a known issue is a good start. Then read it again.

    Have you been able to get this looked at yet??

    the fuel/o2 sensor should be waiting for me when I get back from the holidays on monday...

    i don't have my own scan gauge so once i replace the sensor can i get rid of the CEL by unhooking the battery for a couple min?

    also... how many clean reads does it take for a tacoma undo a CEL.

    i dont think that just disconnecting the battery will clear a CEL. i believe you need to physically clear it with a scan tool like the scangauge which is really easy if you can get your hands on one again.
