PO113 Engine Code Chev Equniox

"06 Chev Equinox 3.4 LV6
I am getting a chronic engine code of P0113 (Intake Air Temp Sensor Circuit High Input Pending).

Where is this sensor located?????

I searched all over the intake manifold and air intake and even looked at AZ site and it's not listed.

The code started a few days after I blocked my EGR Valve port with a metal gasket. ( I was having P0405 Codes and wanted to eliminate the faulty EGR Valve)
I removed the metal blocking gasket and installed a new EGR Valve but I still keep getting the P0113 code. Is this related to what I did? and where is the Air Intake Temperature Sensor located?

After further research I discovered that the Air Intake Temperature sensor is part if the Mass Air Flow sensor at least I think so.
Please confirm this......

Appears to be separate or at least here's one that would be for your vehicle:

By the looks it would be screwed into your intake manifold or somewhere in the air intake system. Externally it looks a lot like a coolant temp sensor.

Question: That's a pretty young vehicle; have you checked to make sure it's not still under Federal emission system warranty?

Tow Guy, how would I check to see if it's still covered?

I started having problems last summer with the EGR then finally replaced it my cost at $90.00.

The MAF/ AIT sensor is about $70.00....wow it's really adding up.

Last month I forked out $200.00 for a new cooling fan assembly!

Don't like these GM vehicles anymore......next one gonna go back to Fords.

Unfortunately that warranty ONLY applies to California cars, the regular 3yrs/36,000 applies to mine and all other 49 states in the Union. Dealer wants $112.00 for the MAF/AIT sensor, my parts guy wants $95.00 with core......I ordered the the dang part.

Ok......I found what was REALLY causing the P0113.
After wasting $100.00 of my hard earned money on a new MAF/AIT Sensor I further researched online and found several posts with the same problem. In many of GM cars they used a very short harness for the MAF/AIT Sensor and it pulls every time the engine torques eventually breaking the wires just before the connector.
You should have 5.0 volts at the connector using a multimeter with the key in the on position but not running......I had 0.0 volts. After scraping back the insulation I found the broken wire and soldered it. Now I have 5.0 volts at the connector again.
The real rest will be driving it through the day tomorrow to see if the engine light stays out.
