IAT means Intake Air Temp sensor. O2 is reffering to the Oxygen sensor. These are two different sensors on your vehicle. These perform different functions.

1998 lesabre check engine light oxygen sensor bank 1 sensor 2.Wher is it located?


Just because you have a check light on & a code,does not mean
the O2 Sensor is bad.

Bank #1 is always on the side that cylinder #1 is on
Sensor #1 is closest to the engine before in in the converter
inlet
Sensor #2 is the Rear,Downstream or Monitor Sensor
usually in the converter outlet

Just want you to be aware that when you replace it you may still have
the same check light & code & then mabe you wil get lucky

That way of doing things will only work a couple of times

Most GM motors, the #1cyl would be on the motors left side
On a Ford, the front right side

If you have single exhaust it is easy & you may as well do both
O2 sensors

The upstream or front one gets done every 80 to 100,000 miles

The rear ones SELDOM FAIL that is why I'am explaining all this

When engine cold only


(1) I'd concentrate on IAT sensor (intake air temperature sensor) & (2) coolant temperature sensor. Both have a bearing on fuel mixture, based on readings they supply to computer. There is a way of testing them if your handy with a multimeter, but most find it easier to replace them as they are not that expensive.
