    I am installing a cold air intake system and performance chip on my 2006 Chevrolet Silverado. It is either the 5.3L V8, or the 6.0L. I need to know where the intake temperature sensor IAT is located. I cannot find it under the hood. Also need to know which 2 wires are for the IAT and what color they are so i can install this performance chip and intake system.

      The Intake air temp sensor is internal to the Mass Airflow Sensor (MAF).

      It cannot be accessed separately.
      The wires for it are…
      Sensor signal- TAN, terminal B
      Low reference- Black, terminal A

        Don’t bother with the “performance chip”. It’s not really a chip at all, it’s just a resistor that is placed across the IAT to fool the engine into thinking the air temperature is colder than it is. Best possible scenario is that it will just make your fuel mileage worse. You’ve just wasted your money.

    I’ve have the same problem my 01 sierra 5.3 cranks but those not start. I’ve checked the fuel pressure and its a 50 psi. I checked all the fuses under the hood and in the cabin and all of them are ok. I’ve also changed the spark plugs and wires and its doing the same cranks but wont start what could be wrong?
