Hey im having problems with my IAT sensor
P0112 Intake Air Temperature Circuit Low Input
Pops up whenever its put on the machine, which throws my check engine light on..
Well the sensor was just replaced. Im not understanding how or why its throwing low input code up..
Any thoughts guys?
thanks

does it come right back on after you reset the ecu (disconnect the battery). Or does it take a little. Im just wondering if this is an intermittant problem or something thats constant. Are there any performance issues?

Scubba.steve -> RE: Check Engine Light (1/18/2008 8:53:47 AM)

Comes back on within 5 minutes of clearing the code.
Everynow and then it takes it a minute to start up.
But when i unplug some sensor right beside,(Right where my ait intake goes in) It starts right up
Havent tried clearing the code then disconecting the battery though.
No performance issues, the car screams threw knoxville.

Check the wiring for the sensor.  You might have a broken wire to the pcm.

Scubba.steve -> RE: Check Engine Light (1/20/2008 3:03:28 PM)

All wiring looks fine, unless 1 is broken off inside

Lol you cant tell a wire is good by looking at it, try ohming the wiring from the sensor to the ecu.

if you get a haynes manual it'll tell you how to test the sensors if you dunno how which it sounds like

Scubba.steve -> RE: Check Engine Light (1/20/2008 6:57:02 PM)

Thank you, i have the haynes manual, took less than 5minutes schimming through it and found what i needed.
Now just need a meter

lhausi2 -> RE: Check Engine Light (1/23/2008 6:23:56 PM)

you can buy a half way decent one at napa or autozone , for like 40 bucks, and you can use it for a whole lot more than just resistance

Scubba.steve -> RE: Check Engine Light (1/23/2008 8:15:35 PM)

well i took the car to midas, they told me that it was a sensor that was supposed to be on my cold air intake,yet they couldnt find the wire and said someone had ripped it out. I think they are full of $hit. Im just going to replace the one i have.
