P0113 Intake Air Temperature circuit high


New member
My SUV has this code. Cold, key on engine off, the Toque app says coolant temp was 70 but the IAT is 95. The 95 degree F goes down if I turn on the engine, but not same as outside air temp.

At 70, the resistant between pin 5 and 6 of the MAF is 2 Kohm (77 degree 1.8 to 2.2 kohm). That appears to be within specs.

The voltage (key on, engine off) between connector's pin 5 and ground is 4.84 volt.

Is this volt too low or within spec of (5volt?).

The voltage of the ambient temp sensor to ground (different circuit I believe) is also about 4.84 volt.

The service manual says check the 3 ground wires. 2 under the dash panel and 1 near the blower motor (I suppose is near the glove box).

Can you one please give me some direction here?

Is the above voltage (4.85 v) within spec?

How do I access these ground wires without remove the instrument panel? I am thinking of only removing the panel directly below the steering column. Am I going the right path?
