IM back! OK my GFs car is spitting out this...

DTC 23 - Intake Air Temperature (IAT) Sensor Circuit ( Voltage High, Low Temp)

Her dad replaced the Radiator fans or motors, Im not sure which ones he did. The SES light has come on ever since. Well were gonna try to reset the light and see if that works. If it doesnt, does anyone have any ideas how to fix this??

UPDATE: That didnt work, what can I do?

ok another UPDATE, thru lookin around Im guessing her IAT Sensor has gone bad. 3 Questions:

1. How much is this part
2. Is it hard to replace myself?
3. Any Guides on how to do this?

I really need to get this done ASAP she needs to have the car properly inspected soon.


sorry, more updates:

I called O'Reileys, they didnt list having a IAT Sensor, The only thing he showed having was an AIR CHARGE TEMPATURE SENSOR for $6.99. Is this the same exact part I need to get for her car?? TIA.

I posted a pic of the part up in the other thread, but I'll try to help with your Q's here.

1) I'm not sure how much the part is, but it's probably not too bad. Might call the local saturn dealer and ask - some parts aren't availible through parts stores, or aren't as good of quality.
2) it's not hard at all, I don't think. I took mine off yesterday just to check it (and learn how to do it before I have to). Not sure if yours will be exactly the same as mine, since your car is a bit older, but a lot is the same. On mine, the wire harness has 2 prongs on it. Easy to take off with a flathead prying just a tiny bit on one side while using my fingernail on the other. Comes right off. Once that's off, you just put a wrench (I think 13mm) on and take it off. It's in a kinda tight spot, so be patient while you're taking it off. If you want better access, you could take the airbox off, but that is a lot more disassembly.
3) Hope to have a more thorough guide soon. If you have a digital camera, you could take pics of each step and create one - it'd be a great help to the site!

I have my phone, Ill try to take pics with it for this. I appreciate the help so far. I got the part, it was $6.99 at O'Reiley's Auto Parts. It was listed under Air Charge Tempature Sensor. I have to wait until tomorrow for this, its my GFs car and shes at home. Im going tomorrow to do this.

Recent rad work. Very good chance that the sensor was unplugged and not plugged back in or the wiring for it is damaged.
