2009 - X Premium - P0113 Won’t clear?

Howdy all,

recently changed my spark plugs - confirmed platinum and not fake and confident in that job. Immediately after changing, got the check engine trifecta with corresponding code P0113 (Intake Air Temp Sensor 1 Circuit High).

Tried clearing the code with the OBD2 but no luck. Pressed “erase” on the OBD2 but the code didn’t even clear then reappear. Then swapped out the mass air flow sensor with no luck.

Any suggestions on where else to look to clear the code?

The IAT and MAF sensors on my 2010 are the same I would believe they are both combined in yours aswell they are pretty easy to find and get to right behind the airbox. Hopefully yours just has a loose or dirty conection if any pins are bent out or just gone you probably need a new MAF if it all looks good I am sure there is some way to easilly check it with a multimeter to make sure there isnt a wire that is out.

What is the reported temperature?

From the 2010 manual:

Higher temperature is lower resistance.

Unsure on temperature. Gotta get something to measure that.
But since you bring up electronics, when I was reconnecting battery i made a mistake and attached negative first… sparks everywhere. I’m thinking i could’ve blown a fuse or relay?

Disconnect the battery and leave it disconnected overnight. With the leads removed from the battery, hold the positive and negative clamps together for some time. Tape them together or something like that. Draining off all the charge from the computer, etc.
